Вопрос экономии времени и удобства окружения разработчика — штука сложная. Работая с Node.js, иногда приходится тестировать своё приложение не только в той версии, которую используете вы, но и в тех, что были выпущены до неё или даже после. В большинстве своём, это касается пакетов (библиотек), которые распространяются через npm. Разумеется, вы можете использовать для этих целей Travis CI, но этот инструмент создан не для этого.
Наиболее простым способом устанавливать и переключать версии Node.js на Linux является использование утилиты nvm. Для разработчиков, которые «сидят» на Windows, существует порт этой утилиты, хотя и менее продвинутый. Разбираемся в управлении версиями Node.js через консоль в Windows.
nvm (Node Version Manager) — это довольно простой скрипт, который позволяет устанавливать, переключать и удалять версии Node.js на лету. Проще говоря, nvm даёт вам возможность держать на одной машине любое количество версий Node.js. При установке новой версии для неё создаётся отдельная директория, например, 5.0.0 или 4.2.2. При переключении версий скрипт подменяет путь до Node.js в PATH.
При этом нужно помнить, что глобальные пакеты для каждой версии свои и никак не пересекаются. Это значит, что если вы глобально установили пакет, используя Node.js версии 4.2.2 и переключились на версию 5.1.0, то этот же пакет вам придётся устанавливать повторно уже для этой версии.
Установка nvm
Напомню, что речь сейчас идёт про Windows, и установить nvm здесь так же «сложно», как и любую другую программу или игру. Для этого вам придётся перейти в репозиторий nvm-windows и загрузить установочный пакет. Далее процедура полностью стандартна, как и для любого другого установочного файла в Windows: выбираете директорию установки и несколько раз кликаете на «Далее».
Установка Node.js
Теперь, когда у вас установлен nvm, пришло время добавить новую версию Node.js. Для этого потребуется прочитать справку, которую можно вызвать, используя команду nvm
.
Сначала посмотрим на список доступных для установки версий Node.js, который можно открыть командой $ nvm list available
. В этом списке доступны как стабильные, так и нестабильные релизы.
Обратите внимание, что здесь не хватает 5-ой версии Node.js. Дело в том, что создатель nvm для Windows ещё не подготовил новый релиз, добавляющий 5-ую версию Node.js в этот список.
Итак, установим последнюю версию Node.js четвертой ветки. Для этого, к сожалению, потребуется полностью прописать версию Node.js, хотя в версии под Linux и OSX можно просто указывать мажорную цифру (4 или 5).
$ nvm install 4.2.2
Тоже самое можно проделать с пятой веткой:
$ nvm install 5.1.0
Помимо версии, при установке есть возможность указать разрядность, например, для установки Node.js 5.1.0 32-битной разрядности следует выполнить
$ nvm install 5.1.0 32
Переключение версий
Посмотрим на список уже установленных версий Node.js на вашей машине, выполнив в консоли команду $ nvm list
:
Для того, чтобы начать использовать Node.js версии 4.2.2, нужно прописать в консоли $ nvm use 4.2.2
. После этого из консоли станет доступна именно эта версия Node.js и поставляемая вместе с ней версия npm:
Соответственно, чтобы переключиться на Node.js версии 5.1.0, нужно выполнить команду:
$ nvm use 5.1.0
Теперь, когда вы выполняете команду $ nvm list
, в выводе будет присутствовать указатель текущей версии:
Создание синонимов
Я вынужден был создать этот заголовок в виду того, что «настоящий» nvm позволяет назначать установленным версиям Node.js синонимы. К сожалению, пока что nvm для Windows не умеет этого.
Немного про глобальные пакеты
Как я уже говорил в начале, nvm разделяет версии Node.js по директориям, и, из-за этого, устанавливаемые глобально пакеты доступны лишь в той версии, в которой они были установлены.
Для примера я установлю свой же пакет windows-ls в версии 4.2.2 и попытаюсь использовать его в версии 5.1.0. В итоге я получаю ошибку, говорящую о том, что такого пакета нет.
Итоги
Все мы знаем, что Windows — это не та платформа, на которую ориентированы разработчики инструментов, которые нужны веб-разработчикам. Примеров, отображающих эту ситуацию довольно много и для каждого они свои, поэтому приводить я их здесь не буду. Рассмотренная в этой статье утилита делает жизнь разработчикам на Windows чуточку лучше, позволяя сконцентрироваться на работе, а не загрузке, установке и удалении различных версий Node.js.
With package.json
— The Maintainable and Portable Way 🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉
Lets each project specify its own version
You can add node
as a dependency in package.json
and control which version is used for a particular project. Upon executing a package.json
«script», npm
(and yarn
) will use that version to run the script instead of the globally installed Node.js.
The node
package accomplishes this by downloading a node
binary for your local system and puts it into the node_modules/.bin
directory.
You can also do this with the npm
(or yarn
) packages but you’ll need to set your PATH
up specifically or use something like npx
that handles it for you.
Ubuntu — The Official Way (manually) 😵
If you’re on node 12 and want to downgrade to node 10, just remove node and follow the instructions for the desired version:
# Remove the version that is currently installed
sudo apt remove -y nodejs
# Setup sources for the version you want
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
# (Re-)Install Node
sudo apt-get install -y nodejs
Windows — The Official Way (manually) 😵
I found myself wanting to downgrade to LTS on Windows from the bleeding edge. If you’re not using a package manager like Chocolatey or a node version manager like nvm
or n
, just download the .msi
for the version you want and install it. You might want to remove the currently installed version via «Add or remove programs» tool in Windows.
Windows Package Manager — winget
🎉🎉
The Open Source Windows Package Manager Way
winget install -e --id OpenJS.Nodejs -v 14.9.0
Chocolatey — The Independent Package Manager Way 🎉
Chocolatey is good for keeping installations up to date easily and it is a common way to install Node.js on Windows. I had to remove the bleeding edge version before installing the LTS version:
choco uninstall nodejs
choco install nodejs-lts
Node Version Manager — The «Screw it, I’ll do it myself!» Way 😢😢😢😭😭😭😭😭
While not very portable or easily maintainable, some developers like manually switching which global version of node is active at any given point in time and think the official ways of doing this are too slow. There are two popular Npm packages that provide helpful CLI interfaces for selecting (and automatically installing) whichever version you want for your system: nvm
and n
. Using either is beyond the scope of this answer.
I highly recommend staying away from this option. Even though it’s popular, it’s an anti-pattern that is sure to cause headaches in the future. Sure, .nvmrc
exists, but this is reinventing something that’s already a part of Npm. Just npm i node
the version you want.

Наш прошлый перевод про новые функции 15-й версии Node.js был очень хорошо принят читателями «Хабра», поэтому сегодня мы решили продолжить тему и рассказать, как настроить NVM с версией Node.js 15 и NPM 7.
Версия Node.js 15 была выпущена 20 октября 2020 года. Она поставляется с npm 7 и множеством новых функций. Вы уже успели опробовать новую версию?
Но подождите минутку! Node.js 15 и npm 7 содержат критические изменения. Не повредит ли тогда обновление существующим проектам?
Теоретически может повредить!
К счастью, у нас есть NVM (Node Version Manager), который избавит нас от этой опасности. Давайте детально рассмотрим данный инструмент, чтобы без проблем обновить версии node.js и npm.
Установка NVM
nvm
управляет версиями node.js и npm. Он устанавливается для конкретного пользователя и может быть вызван отдельно для каждой оболочки. nvm
работает с любой POSIX-совместимой оболочкой (sh, dash, ksh, zsh, bash), в том числе на платформах: unix, macOS и windows WSL.
nvm
можно установить с помощью команд curl или wget:
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
$ wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
Скрипт install.sh
клонирует репозиторий nvm в ~/.nvm
и пытается добавить исходные строки из приведенного ниже фрагмента в нужный файл профиля (~/.bash_profile
, ~/.zshrc
, ~/.profile
или ~/.bashrc
).
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
В ~/.bash_profile
мы видим, что строки добавлены:
export NVM_DIR="/Users/fuje/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Использование NVM
Итак, мы установили nvm. Теперь используем данную команду для установки последней версии node.js:
$ nvm install node
Downloading and installing node v15.4.0...
Downloading https://nodejs.org/dist/v15.4.0/node-v15.4.0-darwin-x64.tar.xz...
######################################################################## 100.0%
Computing checksum with shasum -a 256
Checksums matched!
Now using node v15.4.0 (npm v7.0.15)
В выходных данных из примера выше указано, что npm 7.0.15
используется вместе с node.js 15.4.0
. Проверим:
$ node -v
v15.4.0
$ npm -v
7.0.15
Также мы можем указать нужную версию для установки. Семантический формат версии определяется SemVer:
$ nvm install 10.14.0
Downloading and installing node v10.14.0...
Downloading https://nodejs.org/dist/v10.14.0/node-v10.14.0-darwin-x64.tar.xz...
######################################################################## 100.0%
Computing checksum with shasum -a 256
Checksums matched!
Now using node v10.14.0 (npm v6.4.1)
Если указанная версия уже была установлена, она не переустанавливается:
$ nvm install 10.14.0
v10.14.0 is already installed.
Now using node v10.14.0 (npm v6.4.1)
Мы можем вывести на экран все установленные версии:
$ nvm ls
-> v10.14.0
v10.15.0
v10.16.0
v12.16.0
v13.9.0
v15.4.0
system
default -> 12.16.0 (-> v12.16.0)
node -> stable (-> v15.4.0) (default)
stable -> 15.4 (-> v15.4.0) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/fermium (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.23.0 (-> N/A)
lts/erbium -> v12.20.0 (-> N/A)
lts/fermium -> v14.15.1 (-> N/A)
В приведенных выше примерах вывода символ ->
указывает, что текущая версия node.js — 10.14.0
. Стрелка также представляет значения для default
(12.16.0
), node
(15.4.0
) и stable
(15.4.0
).
nvm use
заменяет текущую версию:
$ nvm use 12.16.0
Now using node v12.16.0 (npm v6.14.8)
$ nvm use 10.16.0
Now using node v10.16.0 (npm v6.14.5)
$ nvm use 13.9.0
Now using node v13.9.0 (npm v6.13.7)
$ nvm use default
Now using node v12.16.0 (npm v6.14.8)
$ nvm use node
Now using node v15.4.0 (npm v7.0.15)
$ nvm use stable
Now using node v15.4.0 (npm v7.0.15)
Возможно, вы спросите, как так получилось, что v10.16.0
использует более позднюю версию npm, чем v13.9.0
. Эту задачу можно решить с помощью следующих команд:
$ nvm use 10.16.0
$ npm install -g npm@6.14.5
Данная команда позволяет получить последнюю поддерживаемую версию npm для текущей версии Node.js:
$ nvm install-latest-npm
nvm use
устанавливает нужную версию только для текущей оболочки. Если вы измените оболочку, только что обновленная версия node.js будет потеряна.
Как сделать определенную версию Node.js постоянной?
Версия по умолчанию — такая версия, которая распространяется на все оболочки.
Команда nvm alias
позволяет установить версию по умолчанию.
$ nvm alias default 10.16.0
Для удобства можно создать файл .nvmrc
, который принимает формат SemVer, node
или default
. После этого nvm use
, nvm install
, nvm exec
, nvm run
и nvm which
будут использовать версию, указанную в файле .nvmrc
, если в командной строке не указана другая.
$ cat .nvmrc
15.4.0
$ nvm use
Found '/Users/fuje/.nvmrc' with version <15.4.0>
Now using node v15.4.0 (npm v7.0.15)
Мы можем проверить текущую версию с помощью следующей команды:
$ nvm current
v15.4.0
ls-remote
выводит на экран все доступные версии, но будьте готовы к очень длинному списку.
$ nvm ls-remote
Обратим внимание, что название версии в сокращенной форме значительно сокращает весь список.
$ nvm ls-remote 15
v15.0.0
v15.0.1
v15.1.0
v15.2.0
v15.2.1
v15.3.0
-> v15.4.0
nvm which
указывает путь к исполняемому файлу, где nvm
был установлен. Мы установили такие версии node.js, как 10.14.0
, 10.15.0
и 10.16.0
. Вот результаты nvm which
:
$ nvm which 10.14.0
/Users/fuje/.nvm/versions/node/v10.14.0/bin/node
$ nvm which 10.15.0
/Users/fuje/.nvm/versions/node/v10.15.0/bin/node
$ nvm which 10.16.0
/Users/fuje/.nvm/versions/node/v10.16.0/bin/node
$ nvm which 10.15
/Users/fuje/.nvm/versions/node/v10.15.0/bin/node
$ nvm which 10.12
N/A: version "v10.12" is not yet installed.
You need to run "nvm install 10.12" to install it before using it.
$ nvm which 10
/Users/fuje/.nvm/versions/node/v10.16.0/bin/node
Указанную версию Node.js можно использовать непосредственно для запуска приложений:
$ nvm run 10.15.0 app.js
Как вариант, данная команда запускает node app.js
с переменной PATH, указывающей на версию 10.15.0
.
$ nvm exec 10.15.0 node app.js
Если вам нужно больше nvm-команд, запустите команду help
:
$ nvm --help
Обновление NVM
Мы можем использовать nvm
для обновления node.js и npm. Но как обновить сам nvm
?
Давайте попробуем!
Перед обновлением у нас установлен nvm
0.34.0
.
Обновляем до версии 0.37.2.
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 13527 100 13527 0 0 23046 0 --:--:-- --:--:-- --:--:-- 23083
=> nvm is already installed in /Users/fuje/.nvm, trying to update using git
=> => Compressing and cleaning up git repository
=> nvm source string already in /Users/fuje/.bash_profile
=> bash_completion source string already in /Users/fuje/.bash_profile
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Как указано в выводе, нам нужно закрыть и снова открыть терминал, чтобы использовать новую версию:
$ nvm --version
0.37.2
По сравнению с версией 0.34.0
, в версии 0.37.2
добавлена функция nvm set-colors
для вывода на консоль.
По умолчанию nvm ls
показывает следующие цвета:
Установим новые цвета:
$ nvm set-colors cgYmW
nvm ls
отображает вывод с новыми цветами:
Заключение
nvm
упрощает управление версиями node.js и npm. Теперь мы точно готовы перейти на node.js 15 и npm 7. Надеюсь, статья была полезной. Другие публикации автора можно найти здесь.

Intro
nvm
allows you to quickly install and use different versions of node via the command line.
Example:
$ nvm use 16 Now using node v16.9.1 (npm v7.21.1) $ node -v v16.9.1 $ nvm use 14 Now using node v14.18.0 (npm v6.14.15) $ node -v v14.18.0 $ nvm install 12 Now using node v12.22.6 (npm v6.14.5) $ node -v v12.22.6
Simple as that!
About
nvm is a version manager for node.js, designed to be installed per-user, and invoked per-shell. nvm
works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and windows WSL.
Installing and Updating
Install & Update Script
To install or update nvm, you should run the install script. To do that, you may either download and run the script manually, or use the following cURL or Wget command:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
Running either of the above commands downloads a script and runs it. The script clones the nvm repository to ~/.nvm
, and attempts to add the source lines from the snippet below to the correct profile file (~/.bash_profile
, ~/.zshrc
, ~/.profile
, or ~/.bashrc
).
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
Additional Notes
-
If the environment variable
$XDG_CONFIG_HOME
is present, it will place thenvm
files there. -
You can add
--no-use
to the end of the above script (…nvm.sh --no-use
) to postpone usingnvm
until you manuallyuse
it. -
You can customize the install source, directory, profile, and version using the
NVM_SOURCE
,NVM_DIR
,PROFILE
, andNODE_VERSION
variables.
Eg:curl ... | NVM_DIR="path/to/nvm"
. Ensure that theNVM_DIR
does not contain a trailing slash. -
The installer can use
git
,curl
, orwget
to downloadnvm
, whichever is available.
Troubleshooting on Linux
On Linux, after running the install script, if you get nvm: command not found
or see no feedback from your terminal after you type command -v nvm
, simply close your current terminal, open a new terminal, and try verifying again.
Alternatively, you can run the following commands for the different shells on the command line:
bash: source ~/.bashrc
zsh: source ~/.zshrc
ksh: . ~/.profile
These should pick up the nvm
command.
Troubleshooting on macOS
Since OS X 10.9, /usr/bin/git
has been preset by Xcode command line tools, which means we can’t properly detect if Git is installed or not. You need to manually install the Xcode command line tools before running the install script, otherwise, it’ll fail. (see #1782)
If you get nvm: command not found
after running the install script, one of the following might be the reason:
-
Since macOS 10.15, the default shell is
zsh
and nvm will look for.zshrc
to update, none is installed by default. Create one withtouch ~/.zshrc
and run the install script again. -
If you use bash, the previous default shell, your system may not have
.bash_profile
or.bashrc
files where the command is set up. Create one of them withtouch ~/.bash_profile
ortouch ~/.bashrc
and run the install script again. Then, run. ~/.bash_profile
or. ~/.bashrc
to pick up thenvm
command. -
You have previously used
bash
, but you havezsh
installed. You need to manually add these lines to~/.zshrc
and run. ~/.zshrc
. -
You might need to restart your terminal instance or run
. ~/.nvm/nvm.sh
. Restarting your terminal/opening a new tab/window, or running the source command will load the command and the new configuration. -
If the above didn’t help, you might need to restart your terminal instance. Try opening a new tab/window in your terminal and retry.
If the above doesn’t fix the problem, you may try the following:
-
If you use bash, it may be that your
.bash_profile
(or~/.profile
) does not source your~/.bashrc
properly. You could fix this by addingsource ~/<your_profile_file>
to it or follow the next step below. -
Try adding the snippet from the install section, that finds the correct nvm directory and loads nvm, to your usual profile (
~/.bash_profile
,~/.zshrc
,~/.profile
, or~/.bashrc
). -
For more information about this issue and possible workarounds, please refer here
Note For Macs with the M1 chip, node started offering arm64 arch darwin packages since v16.0.0 and experimental arm64 support when compiling from source since v14.17.0. If you are facing issues installing node using nvm
, you may want to update to one of those versions or later.
Ansible
You can use a task:
- name: Install nvm ansible.builtin.shell: > curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash args: creates: "{{ ansible_env.HOME }}/.nvm/nvm.sh"
Verify Installation
To verify that nvm has been installed, do:
which should output nvm
if the installation was successful. Please note that which nvm
will not work, since nvm
is a sourced shell function, not an executable binary.
Note: On Linux, after running the install script, if you get nvm: command not found
or see no feedback from your terminal after you type command -v nvm
, simply close your current terminal, open a new terminal, and try verifying again.
Important Notes
If you’re running a system without prepackaged binary available, which means you’re going to install nodejs or io.js from its source code, you need to make sure your system has a C++ compiler. For OS X, Xcode will work, for Debian/Ubuntu based GNU/Linux, the build-essential
and libssl-dev
packages work.
Note: nvm
also support Windows in some cases. It should work through WSL (Windows Subsystem for Linux) depending on the version of WSL. It should also work with GitBash (MSYS) or Cygwin. Otherwise, for Windows, a few alternatives exist, which are neither supported nor developed by us:
- nvm-windows
- nodist
- nvs
Note: nvm
does not support Fish either (see #303). Alternatives exist, which are neither supported nor developed by us:
- bass allows you to use utilities written for Bash in fish shell
- fast-nvm-fish only works with version numbers (not aliases) but doesn’t significantly slow your shell startup
- plugin-nvm plugin for Oh My Fish, which makes nvm and its completions available in fish shell
- fnm — fisherman-based version manager for fish
- fish-nvm — Wrapper around nvm for fish, delays sourcing nvm until it’s actually used.
Note: We still have some problems with FreeBSD, because there is no official pre-built binary for FreeBSD, and building from source may need patches; see the issue ticket:
- [#900] [Bug] nodejs on FreeBSD may need to be patched
- nodejs/node#3716
Note: On OS X, if you do not have Xcode installed and you do not wish to download the ~4.3GB file, you can install the Command Line Tools
. You can check out this blog post on how to just that:
- How to Install Command Line Tools in OS X Mavericks & Yosemite (Without Xcode)
Note: On OS X, if you have/had a «system» node installed and want to install modules globally, keep in mind that:
- When using
nvm
you do not needsudo
to globally install a module withnpm -g
, so instead of doingsudo npm install -g grunt
, do insteadnpm install -g grunt
- If you have an
~/.npmrc
file, make sure it does not contain anyprefix
settings (which is not compatible withnvm
) - You can (but should not?) keep your previous «system» node install, but
nvm
will only be available to your user account (the one used to install nvm). This might cause version mismatches, as other users will be using/usr/local/lib/node_modules/*
VS your user account using~/.nvm/versions/node/vX.X.X/lib/node_modules/*
Homebrew installation is not supported. If you have issues with homebrew-installed nvm
, please brew uninstall
it, and install it using the instructions below, before filing an issue.
Note: If you’re using zsh
you can easily install nvm
as a zsh plugin. Install zsh-nvm
and run nvm upgrade
to upgrade.
Note: Git versions before v1.7 may face a problem of cloning nvm
source from GitHub via https protocol, and there is also different behavior of git before v1.6, and git prior to v1.17.10 can not clone tags, so the minimum required git version is v1.7.10. If you are interested in the problem we mentioned here, please refer to GitHub’s HTTPS cloning errors article.
Git Install
If you have git
installed (requires git v1.7.10+):
- clone this repo in the root of your user profile
cd ~/
from anywhere thengit clone https://github.com/nvm-sh/nvm.git .nvm
cd ~/.nvm
and check out the latest version withgit checkout v0.39.3
- activate
nvm
by sourcing it from your shell:. ./nvm.sh
Now add these lines to your ~/.bashrc
, ~/.profile
, or ~/.zshrc
file to have it automatically sourced upon login:
(you may have to add to more than one of the above files)
export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Manual Install
For a fully manual install, execute the following lines to first clone the nvm
repository into $HOME/.nvm
, and then load nvm
:
export NVM_DIR="$HOME/.nvm" && ( git clone https://github.com/nvm-sh/nvm.git "$NVM_DIR" cd "$NVM_DIR" git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" $(git rev-list --tags --max-count=1)` ) && . "$NVM_DIR/nvm.sh"
Now add these lines to your ~/.bashrc
, ~/.profile
, or ~/.zshrc
file to have it automatically sourced upon login:
(you may have to add to more than one of the above files)
export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Manual Upgrade
For manual upgrade with git
(requires git v1.7.10+):
- change to the
$NVM_DIR
- pull down the latest changes
- check out the latest version
- activate the new version
( cd "$NVM_DIR" git fetch --tags origin git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" $(git rev-list --tags --max-count=1)` ) && . "$NVM_DIR/nvm.sh"
Usage
To download, compile, and install the latest release of node, do this:
nvm install node # "node" is an alias for the latest version
To install a specific version of node:
nvm install 14.7.0 # or 16.3.0, 12.22.1, etc
The first version installed becomes the default. New shells will start with the default version of node (e.g., nvm alias default
).
You can list available versions using ls-remote
:
And then in any new shell just use the installed version:
Or you can just run it:
Or, you can run any arbitrary command in a subshell with the desired version of node:
nvm exec 4.2 node --version
You can also get the path to the executable to where it was installed:
In place of a version pointer like «14.7» or «16.3» or «12.22.1», you can use the following special default aliases with nvm install
, nvm use
, nvm run
, nvm exec
, nvm which
, etc:
node
: this installs the latest version ofnode
iojs
: this installs the latest version ofio.js
stable
: this alias is deprecated, and only truly applies tonode
v0.12
and earlier. Currently, this is an alias fornode
.unstable
: this alias points tonode
v0.11
— the last «unstable» node release, since post-1.0, all node versions are stable. (in SemVer, versions communicate breakage, not stability).
Long-term Support
Node has a schedule for long-term support (LTS) You can reference LTS versions in aliases and .nvmrc
files with the notation lts/*
for the latest LTS, and lts/argon
for LTS releases from the «argon» line, for example. In addition, the following commands support LTS arguments:
nvm install --lts
/nvm install --lts=argon
/nvm install 'lts/*'
/nvm install lts/argon
nvm uninstall --lts
/nvm uninstall --lts=argon
/nvm uninstall 'lts/*'
/nvm uninstall lts/argon
nvm use --lts
/nvm use --lts=argon
/nvm use 'lts/*'
/nvm use lts/argon
nvm exec --lts
/nvm exec --lts=argon
/nvm exec 'lts/*'
/nvm exec lts/argon
nvm run --lts
/nvm run --lts=argon
/nvm run 'lts/*'
/nvm run lts/argon
nvm ls-remote --lts
/nvm ls-remote --lts=argon
nvm ls-remote 'lts/*'
/nvm ls-remote lts/argon
nvm version-remote --lts
/nvm version-remote --lts=argon
/nvm version-remote 'lts/*'
/nvm version-remote lts/argon
Any time your local copy of nvm
connects to https://nodejs.org, it will re-create the appropriate local aliases for all available LTS lines. These aliases (stored under $NVM_DIR/alias/lts
), are managed by nvm
, and you should not modify, remove, or create these files — expect your changes to be undone, and expect meddling with these files to cause bugs that will likely not be supported.
To get the latest LTS version of node and migrate your existing installed packages, use
nvm install 'lts/*' --reinstall-packages-from=current
Migrating Global Packages While Installing
If you want to install a new version of Node.js and migrate npm packages from a previous version:
nvm install node --reinstall-packages-from=node
This will first use «nvm version node» to identify the current version you’re migrating packages from. Then it resolves the new version to install from the remote server and installs it. Lastly, it runs «nvm reinstall-packages» to reinstall the npm packages from your prior version of Node to the new one.
You can also install and migrate npm packages from specific versions of Node like this:
nvm install 6 --reinstall-packages-from=5 nvm install v4.2 --reinstall-packages-from=iojs
Note that reinstalling packages explicitly does not update the npm version — this is to ensure that npm isn’t accidentally upgraded to a broken version for the new node version.
To update npm at the same time add the --latest-npm
flag, like this:
nvm install 'lts/*' --reinstall-packages-from=default --latest-npm
or, you can at any time run the following command to get the latest supported npm version on the current node version:
If you’ve already gotten an error to the effect of «npm does not support Node.js», you’ll need to (1) revert to a previous node version (nvm ls
& nvm use <your latest _working_ version from the ls>
, (2) delete the newly created node version (nvm uninstall <your _broken_ version of node from the ls>
), then (3) rerun your nvm install
with the --latest-npm
flag.
Default Global Packages From File While Installing
If you have a list of default packages you want installed every time you install a new version, we support that too — just add the package names, one per line, to the file $NVM_DIR/default-packages
. You can add anything npm would accept as a package argument on the command line.
# $NVM_DIR/default-packages

io.js
If you want to install io.js:
If you want to install a new version of io.js and migrate npm packages from a previous version:
nvm install iojs --reinstall-packages-from=iojs
The same guidelines mentioned for migrating npm packages in node are applicable to io.js.
System Version of Node
If you want to use the system-installed version of node, you can use the special default alias «system»:
nvm use system nvm run system --version
Listing Versions
If you want to see what versions are installed:
If you want to see what versions are available to install:
Setting Custom Colors
You can set five colors that will be used to display version and alias information. These colors replace the default colors.
Initial colors are: g b y r e
Color codes:
r/R = red / bold red
g/G = green / bold green
b/B = blue / bold blue
c/C = cyan / bold cyan
m/M = magenta / bold magenta
y/Y = yellow / bold yellow
k/K = black / bold black
e/W = light grey / white
Persisting custom colors
If you want the custom colors to persist after terminating the shell, export the NVM_COLORS
variable in your shell profile. For example, if you want to use cyan, magenta, green, bold red and bold yellow, add the following line:
export NVM_COLORS='cmgRY'
Suppressing colorized output
nvm help (or -h or --help)
, nvm ls
, nvm ls-remote
and nvm alias
usually produce colorized output. You can disable colors with the --no-colors
option (or by setting the environment variable TERM=dumb
):
nvm ls --no-colors
nvm help --no-colors
TERM=dumb nvm ls
Restoring PATH
To restore your PATH, you can deactivate it:
Set default node version
To set a default Node version to be used in any new shell, use the alias ‘default’:
Use a mirror of node binaries
To use a mirror of the node binaries, set $NVM_NODEJS_ORG_MIRROR
:
export NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist
nvm install node
NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 4.2
To use a mirror of the io.js binaries, set $NVM_IOJS_ORG_MIRROR
:
export NVM_IOJS_ORG_MIRROR=https://iojs.org/dist
nvm install iojs-v1.0.3
NVM_IOJS_ORG_MIRROR=https://iojs.org/dist nvm install iojs-v1.0.3
nvm use
will not, by default, create a «current» symlink. Set $NVM_SYMLINK_CURRENT
to «true» to enable this behavior, which is sometimes useful for IDEs. Note that using nvm
in multiple shell tabs with this environment variable enabled can cause race conditions.
.nvmrc
You can create a .nvmrc
file containing a node version number (or any other string that nvm
understands; see nvm --help
for details) in the project root directory (or any parent directory).
Afterwards, nvm use
, nvm install
, nvm exec
, nvm run
, and nvm which
will use the version specified in the .nvmrc
file if no version is supplied on the command line.
For example, to make nvm default to the latest 5.9 release, the latest LTS version, or the latest node version for the current directory:
$ echo "5.9" > .nvmrc $ echo "lts/*" > .nvmrc # to default to the latest LTS version $ echo "node" > .nvmrc # to default to the latest version
[NB these examples assume a POSIX-compliant shell version of echo
. If you use a Windows cmd
development environment, eg the .nvmrc
file is used to configure a remote Linux deployment, then keep in mind the "
s will be copied leading to an invalid file. Remove them.]
Then when you run nvm:
$ nvm use Found '/path/to/project/.nvmrc' with version <5.9> Now using node v5.9.1 (npm v3.7.3)
nvm use
et. al. will traverse directory structure upwards from the current directory looking for the .nvmrc
file. In other words, running nvm use
et. al. in any subdirectory of a directory with an .nvmrc
will result in that .nvmrc
being utilized.
The contents of a .nvmrc
file must be the <version>
(as described by nvm --help
) followed by a newline. No trailing spaces are allowed, and the trailing newline is required.
Deeper Shell Integration
You can use avn
to deeply integrate into your shell and automatically invoke nvm
when changing directories. avn
is not supported by the nvm
maintainers. Please report issues to the avn
team.
If you prefer a lighter-weight solution, the recipes below have been contributed by nvm
users. They are not supported by the nvm
maintainers. We are, however, accepting pull requests for more examples.
bash
Automatically call nvm use
Put the following at the end of your $HOME/.bashrc
:
cdnvm() { command cd "$@" || return $? nvm_path=$(nvm_find_up .nvmrc | tr -d 'n') # If there are no .nvmrc file, use the default nvm version if [[ ! $nvm_path = *[^[:space:]]* ]]; then declare default_version; default_version=$(nvm version default); # If there is no default version, set it to `node` # This will use the latest version on your machine if [[ $default_version == "N/A" ]]; then nvm alias default node; default_version=$(nvm version default); fi # If the current version is not the default version, set it to use the default version if [[ $(nvm current) != "$default_version" ]]; then nvm use default; fi elif [[ -s $nvm_path/.nvmrc && -r $nvm_path/.nvmrc ]]; then declare nvm_version nvm_version=$(<"$nvm_path"/.nvmrc) declare locally_resolved_nvm_version # `nvm ls` will check all locally-available versions # If there are multiple matching versions, take the latest one # Remove the `->` and `*` characters and spaces # `locally_resolved_nvm_version` will be `N/A` if no local versions are found locally_resolved_nvm_version=$(nvm ls --no-colors "$nvm_version" | tail -1 | tr -d '->*' | tr -d '[:space:]') # If it is not already installed, install it # `nvm install` will implicitly use the newly-installed version if [[ "$locally_resolved_nvm_version" == "N/A" ]]; then nvm install "$nvm_version"; elif [[ $(nvm current) != "$locally_resolved_nvm_version" ]]; then nvm use "$nvm_version"; fi fi } alias cd='cdnvm' cd "$PWD"
This alias would search ‘up’ from your current directory in order to detect a .nvmrc
file. If it finds it, it will switch to that version; if not, it will use the default version.
zsh
Calling nvm use
automatically in a directory with a .nvmrc
file
Put this into your $HOME/.zshrc
to call nvm use
automatically whenever you enter a directory that contains an
.nvmrc
file with a string telling nvm which node to use
:
# place this after nvm initialization! autoload -U add-zsh-hook load-nvmrc() { local nvmrc_path="$(nvm_find_nvmrc)" if [ -n "$nvmrc_path" ]; then local nvmrc_node_version=$(nvm version "$(cat "${nvmrc_path}")") if [ "$nvmrc_node_version" = "N/A" ]; then nvm install elif [ "$nvmrc_node_version" != "$(nvm version)" ]; then nvm use fi elif [ -n "$(PWD=$OLDPWD nvm_find_nvmrc)" ] && [ "$(nvm version)" != "$(nvm version default)" ]; then echo "Reverting to nvm default version" nvm use default fi } add-zsh-hook chpwd load-nvmrc load-nvmrc
fish
Calling nvm use
automatically in a directory with a .nvmrc
file
This requires that you have bass installed.
# ~/.config/fish/functions/nvm.fish function nvm bass source ~/.nvm/nvm.sh --no-use ';' nvm $argv end # ~/.config/fish/functions/nvm_find_nvmrc.fish function nvm_find_nvmrc bass source ~/.nvm/nvm.sh --no-use ';' nvm_find_nvmrc end # ~/.config/fish/functions/load_nvm.fish function load_nvm --on-variable="PWD" set -l default_node_version (nvm version default) set -l node_version (nvm version) set -l nvmrc_path (nvm_find_nvmrc) if test -n "$nvmrc_path" set -l nvmrc_node_version (nvm version (cat $nvmrc_path)) if test "$nvmrc_node_version" = "N/A" nvm install (cat $nvmrc_path) else if test "$nvmrc_node_version" != "$node_version" nvm use $nvmrc_node_version end else if test "$node_version" != "$default_node_version" echo "Reverting to default Node version" nvm use default end end # ~/.config/fish/config.fish # You must call it on initialization or listening to directory switching won't work load_nvm > /dev/stderr
Running Tests
Tests are written in Urchin. Install Urchin (and other dependencies) like so:
There are slow tests and fast tests. The slow tests do things like install node
and check that the right versions are used. The fast tests fake this to test
things like aliases and uninstalling. From the root of the nvm git repository,
run the fast tests like this:
Run the slow tests like this:
Run all of the tests like this:
Nota bene: Avoid running nvm while the tests are running.
Environment variables
nvm exposes the following environment variables:
NVM_DIR
— nvm’s installation directory.NVM_BIN
— where node, npm, and global packages for the active version of node are installed.NVM_INC
— node’s include file directory (useful for building C/C++ addons for node).NVM_CD_FLAGS
— used to maintain compatibility with zsh.NVM_RC_VERSION
— version from .nvmrc file if being used.
Additionally, nvm modifies PATH
, and, if present, MANPATH
and NODE_PATH
when changing versions.
Bash Completion
To activate, you need to source bash_completion
:
[[ -r $NVM_DIR/bash_completion ]] && . $NVM_DIR/bash_completion
Put the above sourcing line just below the sourcing line for nvm in your profile (.bashrc
, .bash_profile
).

Installing nvm on Alpine Linux
In order to provide the best performance (and other optimizations), nvm will download and install pre-compiled binaries for Node (and npm) when you run nvm install X
. The Node project compiles, tests and hosts/provides these pre-compiled binaries which are built for mainstream/traditional Linux distributions (such as Debian, Ubuntu, CentOS, RedHat et al).
Alpine Linux, unlike mainstream/traditional Linux distributions, is based on BusyBox, a very compact (~5MB) Linux distribution. BusyBox (and thus Alpine Linux) uses a different C/C++ stack to most mainstream/traditional Linux distributions — musl. This makes binary programs built for such mainstream/traditional incompatible with Alpine Linux, thus we cannot simply nvm install X
on Alpine Linux and expect the downloaded binary to run correctly — you’ll likely see «…does not exist» errors if you try that.
There is a -s
flag for nvm install
which requests nvm download Node source and compile it locally.
If installing nvm on Alpine Linux is still what you want or need to do, you should be able to achieve this by running the following from you Alpine Linux shell, depending on which version you are using:
Alpine Linux 3.13+
apk add -U curl bash ca-certificates openssl ncurses coreutils python3 make gcc g++ libgcc linux-headers grep util-linux binutils findutils
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
Alpine Linux 3.5 — 3.12
apk add -U curl bash ca-certificates openssl ncurses coreutils python2 make gcc g++ libgcc linux-headers grep util-linux binutils findutils
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
Note: Alpine 3.5 can only install NodeJS versions up to v6.9.5, Alpine 3.6 can only install versions up to v6.10.3, Alpine 3.7 installs versions up to v8.9.3, Alpine 3.8 installs versions up to v8.14.0, Alpine 3.9 installs versions up to v10.19.0, Alpine 3.10 installs versions up to v10.24.1, Alpine 3.11 installs versions up to v12.22.6, Alpine 3.12 installs versions up to v12.22.12, Alpine 3.13 & 3.14 install versions up to v14.20.0, Alpine 3.15 & 3.16 install versions up to v16.16.0 (These are all versions on the main branch). Alpine 3.5 — 3.12 required the package python2
to build NodeJS, as they are older versions to build. Alpine 3.13+ requires python3
to successfully build newer NodeJS versions, but you can use python2
with Alpine 3.13+ if you need to build versions of node supported in Alpine 3.5 — 3.15, you just need to specify what version of NodeJS you need to install in the package install script.
The Node project has some desire but no concrete plans (due to the overheads of building, testing and support) to offer Alpine-compatible binaries.
As a potential alternative, @mhart (a Node contributor) has some Docker images for Alpine Linux with Node and optionally, npm, pre-installed.
Uninstalling / Removal
Manual Uninstall
To remove nvm
manually, execute the following:
Edit ~/.bashrc
(or other shell resource config) and remove the lines below:
export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm [[ -r $NVM_DIR/bash_completion ]] && . $NVM_DIR/bash_completion
Docker For Development Environment
To make the development and testing work easier, we have a Dockerfile for development usage, which is based on Ubuntu 18.04 base image, prepared with essential and useful tools for nvm
development, to build the docker image of the environment, run the docker command at the root of nvm
repository:
$ docker build -t nvm-dev .
This will package your current nvm repository with our pre-defined development environment into a docker image named nvm-dev
, once it’s built with success, validate your image via docker images
:
$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE nvm-dev latest 9ca4c57a97d8 7 days ago 650 MB
If you got no error message, now you can easily involve in:
$ docker run -h nvm-dev -it nvm-dev
nvm@nvm-dev:~/.nvm$
Please note that it’ll take about 8 minutes to build the image and the image size would be about 650MB, so it’s not suitable for production usage.
For more information and documentation about docker, please refer to its official website:
- https://www.docker.com/
- https://docs.docker.com/
Problems
-
If you try to install a node version and the installation fails, be sure to run
nvm cache clear
to delete cached node downloads, or you might get an error like the following:curl: (33) HTTP server doesn’t seem to support byte ranges. Cannot resume.
-
Where’s my
sudo node
? Check out #43 -
After the v0.8.6 release of node, nvm tries to install from binary packages. But in some systems, the official binary packages don’t work due to incompatibility of shared libs. In such cases, use
-s
option to force install from source:
- If setting the
default
alias does not establish the node version in new shells (i.e.nvm current
yieldssystem
), ensure that the system’s nodePATH
is set before thenvm.sh
source line in your shell profile (see #658)
macOS Troubleshooting
nvm node version not found in vim shell
If you set node version to a version other than your system node version nvm use 6.2.1
and open vim and run :!node -v
you should see v6.2.1
if you see your system version v0.12.7
. You need to run:
sudo chmod ugo-x /usr/libexec/path_helper
More on this issue in dotphiles/dotzsh.
nvm is not compatible with the npm config «prefix» option
Some solutions for this issue can be found here
There is one more edge case causing this issue, and that’s a mismatch between the $HOME
path and the user’s home directory’s actual name.
You have to make sure that the user directory name in $HOME
and the user directory name you’d see from running ls /Users/
are capitalized the same way (See this issue).
To change the user directory and/or account name follow the instructions here
Homebrew makes zsh directories unsecure
zsh compinit: insecure directories, run compaudit for list. Ignore insecure directories and continue [y] or abort compinit [n]? y
Homebrew causes insecure directories like /usr/local/share/zsh/site-functions
and /usr/local/share/zsh
. This is not an nvm
problem — it is a homebrew problem. Refer here for some solutions related to the issue.
Macs with M1 chip
Experimental support for the M1 architecture was added in node.js v15.3 and full support was added in v16.0.
Because of this, if you try to install older versions of node as usual, you will probably experience either compilation errors when installing node or out-of-memory errors while running your code.
So, if you want to run a version prior to v16.0 on an M1 Mac, it may be best to compile node targeting the x86_64
Intel architecture so that Rosetta 2 can translate the x86_64
processor instructions to ARM-based Apple Silicon instructions.
Here’s what you will need to do:
-
Install Rosetta, if you haven’t already done so
$ softwareupdate --install-rosetta
You might wonder, «how will my M1 Mac know to use Rosetta for a version of node compiled for an Intel chip?».
If an executable contains only Intel instructions, macOS will automatically use Rosetta to translate the instructions. -
Open a shell that’s running using Rosetta
Note: This same thing can also be accomplished by finding the Terminal or iTerm App in Finder, right clicking, selecting «Get Info», and then checking the box labeled «Open using Rosetta».
Note: This terminal session is now running in
zsh
.
Ifzsh
is not the shell you typically use,nvm
may not besource
‘d automatically like it probably is for your usual shell through your dotfiles.
If that’s the case, make sure to sourcenvm
.$ source "${NVM_DIR}/nvm.sh"
-
Install whatever older version of node you are interested in. Let’s use 12.22.1 as an example.
This will fetch the node source code and compile it, which will take several minutes.$ nvm install v12.22.1 --shared-zlib
Note: You’re probably curious why
--shared-zlib
is included.
There’s a bug in recent versions of Apple’s systemclang
compiler.
If one of these broken versions is installed on your system, the above step will likely still succeed even if you didn’t include the--shared-zlib
flag.
However, later, when you attempt tonpm install
something using your old version of node.js, you will seeincorrect data check
errors.
If you want to avoid the possible hassle of dealing with this, include that flag.
For more details, see this issue and this comment -
Exit back to your native shell.
Note: If you selected the box labeled «Open using Rosetta» rather than running the CLI command in the second step, you will see
i386
here.
Unless you have another reason to have that box selected, you can deselect it now. -
Check to make sure the architecture is correct.
x64
is the abbreviation forx86_64
, which is what you want to see.$ node -p process.arch x64
Now you should be able to use node as usual.
WSL Troubleshooting
If you’ve encountered this error on WSL-2:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- 0:00:09 --:--:-- 0curl: (6) Could not resolve host: raw.githubusercontent.com
It may be due to your antivirus, VPN, or other reasons.
Where you can ping 8.8.8.8
while you can’t ping google.com
This could simply be solved by running this in your root directory:
sudo rm /etc/resolv.conf sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf' sudo bash -c 'echo "[network]" > /etc/wsl.conf' sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf' sudo chattr +i /etc/resolv.conf
This deletes your resolve.conf
file thats automatically generated when u run WSL, creates a new file and puts nameserver 8.8.8.8
, then creates a wsl.conf
file and adds [network]
and generateResolveConf = false
to prevent auto generation of that file.
You can check the contents of the file by running:

Встречались ли вы с ситуацией, когда какой-нибудь ваш проект требует версию node.js меньше, чем у вас установлена. На UNIX системах переключить версию node сравнительно легко. А вот для Windows немного сложнее. Ниже описан один из самых лёгких способов это сделать.
Для начала качаем NVM (Node Version Manager) для Windows по ссылке. Там среди прочей информации о версиях, будут предложены несколько инсталлях, в том числе для обновления уже установленного NVM. Для случая «с нуля» выбираем nvm-setup.zip (или как он будет зваться в дальнейшем) и ставим. Дальше лучше перезагрузить систему.
Свидетельством успешной установки будет работоспособность в терминале команды nvm version. Она должна нам вывести нечто подобное:
nvm version
1.1.9
Теперь, если мы проверим наличие всех установленных версий node и текущую, введём nvm list
nvm list
16.13.1
Допустим, нам для проекта нужна версия node 14. Ставим её:
nvm install 14
Установится версия 14.19.0 — последняя в серии 14. Если хотим установить конкретную версию, указываем это в nvm-команде.
Сейчас, если мы посмотрим список установленных версий, то увидим следующее:
nvm list
16.13.1
14.19.0
Чтобы переключиться на нужную версию из уже имеющихся, вводим:
nvm use 14.19.0
Теперь эта версия будет актуальной и чтобы вернуться к прежней, используем те же команды.
Будь в курсе свежих новостей
Один из простейших путей как установить Node.Js это пойти на официальный сайт, скачать установочный файл и установить его. Позже разработчики столкнулись с ситуацией, когда им нужно сменить версию Node.js на другую или обновить текущую версию.
Это все еще возможно — установить другую версию с официального сайта, но как много нод уже установлено в системе?
Может быть это хорошее время для удаления их всех и настроить возможность системе переключаться между нодами за секунды, всегда зная количество установленных версий и иметь возможность удалить любые из них одной простой командой.

Обо всем по порядку, мы должны удалить старые версии ноды и все связанное с этим. Вы счастливчик, если вы установили прошлые версии с помощью Homebrew. Метод Homebrew это один из простейших вариантов для установки и удаления ноды на маке.
brew uninstall —force node
Напишите эту команду в терминале. Brew удалит все установленные версии Node.Js
После этого, лучше всего, запустить brew cleanup, это удалит все неиспользуемые зависимости и папки.
brew cleanup
Если ваша Node.js была установлена по другому, это не проблема. Вы можете удалить вручную. Есть куча папок, они могут быть удалены одна за одной через файндер или терминал.
Список папок, где находятся Node.js и npm
- node и/или node_modules в папке /usr/local/lib
- node и/или node_modules в папке /usr/local/include
- node, node-debug, и node-gyp в /usr/local/bin
- .npmrc в вашей домашней директории (Это настройки npm, не удаляйте этот файл, если хотите далее переустановить Node.js)
- .npm в вашей домашней директории
- .node-gyp в вашей домашней директории
- .node_repl_history в вашей домашней директории
- node* в /usr/local/share/man/man1/
- npm* в /usr/local/share/man/man1/
- node.d в /usr/local/lib/dtrace/
- node в /opt/local/bin/
- node в /opt/local/include/
- node_modules в /opt/local/lib/
- node в /usr/local/share/doc/
- node.stp в /usr/local/share/systemtap/tapset/
В случае, если вы не хотите вручную искать и удалять все эти папки и файлы, вы можете ввести одну простую команду в терминал:
sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}
Эта команда не трогает вашу домашнюю директорию, так что в дальнейшем вы можете сами решить, что делать с сохранившимися файлами.
Сейчас мы можем удалить все глобальные пакеты, установленные с npm
rm -rf ~/.npm
После всех этих команд, Node.js и npm будут полностью удалены с вашего компьютера.
Как установить Node.js на Mac OS
После очистки, мы можем продолжить с установкой новой версии Node.js. Но мы сделаем это не прямым путем. Потому что если мы сделаем это по обычному, мы все еще будем иметь ту же проблему с кучей версий в будущем.
У данного скрипта есть единственная зависимость — установленная Command Line Tools. Если у вас все еще это не установлено, вы должны запустит команду в терминале:
xcode-select —install
Итак, мы готовы установить NVM. Простейший путь это сделать — .sh скрипт.
Скачать и установить данный скрипт мы можем с помощью следующей команды:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
0.37.2 — последняя версия на день написания статьи. Версия может быть проверена на странице NVM в GitHub
Конечно, это может быть установлено вручную. Вы нужно склонировать репозиторий и добавить необходимы файлы в PATH. Детальная инструкция описана в NVM ReadMe. Это будет полезно если вам нужно использовать NVM в CI пайплайн. Я бы рекомендовал добавить NVM в Docker image, который использует ваш пайплайн.
Не забудьте перезапустить окно терминала для обновления переменных окружения
Мы почти закончили. Сейчас мы легко можем установить любую версию Node.js. Для примера, эта команда установит самую свежую версию:
nvm install node
Если вы хотите установит LTS версию, но с последней версией npm, сделайте следующее:
nvm install —lts —latest-npm
Используя флаги, вроде —lts вы можете использовать любую версию.
nvm install 8.9.1 # or 10.10.0, 12, etc
Для того, что бы увидеть список установленных версий, вам нужно запустить команду:
nvm list
После установки, вам нужно выбрать дефолтную версию для вашей системы:
nvm use —lts
Что о пользователях Windows?
Для windows доступен похожий скрипт: Node Version Manager (nvm) for Windows. Это другой проект, который делает то же самое. Вы так-же можете устанавливать/удалять/выводить список и переключать любые версии Node.js
Итоги
С NVM вы получаете:
- Простую установку/удаление любой версии Node.js
- Лучший скрипт для переключения между нодами.
- Удаление такое же простое, как и установка
Вы почувствуете это в будущем, особенно, когда в следующий раз будете обновлять свою Node.js.

Node.js is one of the most popular development platforms nowadays. It allows developers to create server-side applications using JavaScript. Updating Node versions can be tricky, but it’s crucial for your development environment.
This blog post will take you through updating Node.js on Mac, Windows, and Linux. We’ll also give you some tips to make the process as smooth as possible. First, we’ll discuss why keeping your Node up-to-date is essential.
Let’s get started!
Why is it important to keep Node up-to-date?
Node.js is an open-source platform. New features, bug fixes, and security updates are constantly released. Newer versions of Node.js will have better performance, stability, and security. That’s why it’s essential to keep up-to-date with the latest version of Node
Why update the Node version, if a project already runs smoothly?
Keeping your Node up-to-date ensures your code runs with the latest security and bug fixes and gets access to the latest features. If you don’t keep your Node up-to-date, it could lead to security vulnerabilities and other issues. Even if your code is impeccable, any third-party code integrated into your work — directly or indirectly — can have its own security faults.
Now that we know how important it is to update Node, how do you update it? Let’s look at updating Node on Mac, Windows, and Linux.
There are a few ways to update Node on Mac and Windows. We’ll talk about using a package manager such as NPM or manually downloading the latest version and installing it yourself.
Using NPM:
To update Node using NPM, do the following:
- Open the Terminal and check your current Node version:
node -v - Install n package using the following command:
npm install -g n
This command will install a tool called «n» which you can use to update Node easily. - To update Node, run the following command in your terminal:
n latest
This command will install the latest version of Node on your system. - Now you can verify that your update is complete by rechecking your Node version:
node -v
You can also manually download and install the latest Node version from the official website.
How to Update Node Versions on Linux
Updating Node on Linux is a bit different from how it’s done on Windows and Mac. To update Node, you’ll need to use a package manager such as NVM or APT.
Using nvm:
NVM (Node Version Manager) is a tool that allows you to manage multiple versions of Node on your system. You can use nvm to install, update, and switch between different versions of Node.
To update your version of Node using nvm, do the following:
- Check if you already have nvm installed on your system:
nvm —version - If it’s not installed, install nvm using this command:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash - Once nvm is installed, check your current version of Node by running the following command:
node -v - Then update your version of Node using the following command:
nvm install node —reinstall-packages-from=node - And finally, verify that your update is complete by rechecking your Node version:
node -v
Using APT (Advanced Package Tool):
APT is a package manager for Debian-based Linux distributions such as Ubuntu and Debian. To update Node using APT, do the following:
- First, check your current version of Node by running the following command:
node -v - Then run this command to install the latest version of Node:
sudo apt-get install nodejs - And finally verify that your update is complete by rechecking your Node version:
node -v
These are just a few ways to update Node on Mac, Windows, and Linux. Keep in mind that it’s important to keep up-to-date with the latest version of Node not only for security reasons but also to get access to new features and bug fixes.
Tips For Updating Your Node Version
Updating Node versions can be a simple process. Here are some tips to make it easier:
- Make sure your existing Node version is up to date before upgrading. You may experience issues during the updating process if it still needs to be updated.
- Test any new features or bug fixes on a development environment before deploying them to production. This will help ensure that everything works as expected before making any changes live.
- Ensure your development environment is backed up regularly if anything goes wrong during the upgrade process.
- Keep an eye on the Node release notes for new updates or software changes.
By following these tips and using the above methods, you can ensure that your node version is always up-to-date with the latest features and security patches!
Final Thoughts on Updating Node Version
The benefits of Node.js is countless. From its easy-to-use environment, modern features, and constant updates, Node is a popular choice for developing applications. Keeping your version of Node up-to-date is important to get the best performance, security, and features out of it. With multiple options available such as Mac, Windows, and Linux, updating Node is accessible and can be done quickly with just a few steps.
