Как изменить версию node js mac os

Node.js version 18.3.0 is currently the latest, and yours might differ depending on when you read this article. Web Development is changing rapidly. Development is picking rapidly, and Node.js is shipping out the new version to almost everyone; therefore, it is nice to have the latest version in your development environment to test the new features and make it compatible with other Javascript libraries.

Why you should upgrade the node

You have many reasons why you should update the node to the latest version because the Javascript community is getting bigger, and so is the NPM repository.

All the new JS frameworks and libraries require the latest node.js version because they are built on the newest technology, and to keep up with that. You also need to update all of your outdated libraries, especially Node.js.

Let me give you a scenario if you are using the current date’s latest version of React, which is React 16.2.0, and you have a node.js version of, let’s say, 9.0, then you won’t be able to even install the React.js project due to some outdated libraries of node.js.

You need to update the latest version to work with other JS libraries and frameworks.

Even node.js is improving from its previous version, so there are many reasons to upgrade your node.js to the latest version. Getting left behind will be the never option for you.

To update node version on mac:

1. Using N: An npm-based node version manager.
2. Using Homebrew: Type this command: brew upgrade node
3. Using NVM: A script-based node version manager.

Update Node using N

N is an npm-based node version manager. I assume that you already have some version of the node installed on your machine. You can install the first node version and then run the following command.

sudo npm install -g n.

Assuming you have successfully installed n. It is the simplest way.

The following command will install the latest version of the node. Please hit that command in admin mode.

sudo n latest

It will install the latest version of Node.js.

Update Node version on Mac

To update Node version on Mac, use the brew upgrade node command. The Homebrew is one of the popular package managers for MacOS. If you are using Mac, Homebrew is the package manager you can use to install different packages.

Assuming you have previously installed node with. Then, with the following command, you can get up-to-date with formulae and upgrade to the latest Node.js version.

brew update
brew upgrade node

It will install the latest version of Node.js.

Update Node using NVM

NVM is the script-based node version manager. You can install it easily with the curl and bash one-liner described in the documentation. It’s also available on the Homebrew package manager.

You can install NVM using HomebHomebrewg the following command.

brew install nvm

Now the following command will install the latest version of the node.

nvm install node --reinstall-packages-from=node

The last option installs all the global npm packages to your new version.

This way, the packages like mocha and node-inspector keep working.

Conclusions

Upgrading node to the latest version is kid’s stuff, but if you are running in trouble, you can always switch the way to update it.

If you are running into trouble using Homebrew, update the Homebrew and then install one by one missing dependency. It will work fine only after it has all the required dependencies.

If possible, keep your node.js version updated.

That’s it for this article.

How to create a node.js server

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.

Как удалить Node.Js с Mac OS

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.

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.

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

В случае, если вы не хотите вручную искать и удалять все эти папки и файлы, вы можете ввести одну простую команду в терминал:

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

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:

Итак, мы готовы установить NVM. Простейший путь это сделать — .sh скрипт.

Скачать и установить данный скрипт мы можем с помощью следующей команды:

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:

Если вы хотите установит LTS версию, но с последней версией npm, сделайте следующее:

Используя флаги, вроде —lts вы можете использовать любую версию.

Для того, что бы увидеть список установленных версий, вам нужно запустить команду:

После установки, вам нужно выбрать дефолтную версию для вашей системы:

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:

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

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:

1. Open the Terminal and check your current Node version: 
   node -v 
2. 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.
3. To update Node, run the following command in your terminal:           
   n latest
   This command will install the latest version of Node on your system.
4. 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:

1. Check if you already have nvm installed on your system:  
   nvm —version
2. 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
3. Once nvm is installed, check your current version of Node by running the following command:
   node -v
4. Then update your version of Node using the following command:  
   nvm install node —reinstall-packages-from=node
5. 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:

1. First, check your current version of Node by running the following command:
   node -v
2. Then run this command to install the latest version of Node:    
   sudo apt-get install nodejs
3.  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.

Introduction

Node.js is an open-source JavaScript runtime environment. Since Node.js has an active community of users, minor updates of the software come out every few weeks.

You may be using Node.js as a layer of the MEAN stack or in a different JS framework. Either way, make sure to update Node.js regularly to ensure system security.

There are several ways to install Node.js and NPM. Likewise, there are several ways to update your Node.js version, depending on the operating system running on your machine.

In this article, you will learn how to update to the latest Node.js version on Linux, Windows, and macOS.

3 Ways to Update Node.js to Latest Version on Linux Systems

There are different ways to update Node.js if you are using a Linux-based system. Although using the Node Version Manager is the easiest and most recommended option, you can also update with the local package manager or by downloading the binary packages.

Option 1: Update Node.js with NVM (Node Version Manager)

The best way to upgrade Node.js is with NVM, a practical tool for managing multiple Node.js versions.

1. Start by updating the package repository with the command:

sudo apt update

2. Install NVM using the curl command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

Alternatively, you use wget and run the command:

wget -q0- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

3. Close and reopen the terminal for system to recognize the changes or run the command:

source ~/.bashrc

5. Then, verify if you have successfully installed NVM:

nvm --version

6. Before upgrading Node.js, check which version you have running on the system:

nvm ls

7. Now you can check for newly available releases with:

nvm ls-remote

8. To install the latest version, use the nvm command with the specific Node.js version:

nvm install [version.number]

Option 2: Update Node.js with NPM (Node Package Manager)

As an alternative, you can use Node’s official package manager to update Node.js. NPM is a tool for installing and managing package dependencies.

If you have Node on your system, you have NPM, as well. With the npm command, you can check running Node.js versions and install the latest release.

By adding the n module, you can interactively manage Node.js versions.

1. First, clear the npm cache:

npm cache clean -f

2. Install n, Node’s version manager:

npm install -g n

3. With the n module installed, you can use it to:

Install the latest stable version:

sudo n stable

Install the latest release:

sudo n latest

Install a specific version:

sudo n [version.number]

Option 3: Update Node.js with Binary Packages

Updating Node.js with binary packages is the least recommended option. However, if it is the only way you can upgrade to the latest Node.js version, follow the steps outlined below.

1. Navigate to Node’s official downloads page where you can find all available packages. There you can download the source code or pre-built installer for the LTS versions or the latest release.

2. You can either download the package from your browser or find the version number you need and add it to the wget command:

wget https://nodejs.org/dist/v14.17.0/node-v14.17.0-linux-x64.tar.xz

3. Next, install xz-utils used to extract the binary package:

sudo apt-get install xz-utils

4. Extract and install the package with the command:

sudo tar -C /usr/local --strip-components 1 -xJf node-v14.17.0-linux-x64.tar.xz

Updating Node.js on Windows and macOS follows the same principles.

There are two simple ways to upgrade:

• Download the latest Node.js release from its official download page and install the new Node.js release.
• Install the n module and update Node.js inside the terminal window.

Option 1: Update Node.js on Windows and macOS with Installer

One way to update your Node.js is to go to its official download page and install the newest release. Bz doing so, the system should overwrite the older version with the updated one.

1. Navigate to the Node.js website and click on the latest stable version or the newest current release (with the latest features).

2. After deciding the version, click on the Windows or the macOS Installer, depending on the system you are using. The system downloads the package and stores it in the specified directory.

3. Once the download is complete, run the installer.

4. The Node.js Setup Wizard appears and guides you through the installation.

5. Accept the License Agreement by checking the box and click Next.

6. Choose the destination folder where you want to install Node.js.

7. Node.js allows you to select how you want to install the Node features. Change the way the features are installed by clicking on the icons in the tree.

8. With that, the latest Node.js is ready to install. Click Install to confirm, wait until the installation completes, and click Finish.

9. Check the Node.js version with the command:

node -v

Option 2: Update Node.js on Windows and macOS with NPM

If you want to upgrade Node.js from the command line, use the n model within the npm command. The n feature allows you to interact with different Node.js versions.

1. Before updating the Node.js release, check which version you are currently using with:

node -v

2. Next, clear npm cache with the command:

npm cache clean -f

3. Install n globally:

npm install -g n

4. Now that you have n installed, you can use the module to install the latest stable release of Node.js:

sudo n stable

Alternatively, you can install the Node.js release with the latest features:

sudo n latest

Or, install a specific version number with:

n [version.number]

Conclusion

The best part of open-source technology is its strong community of users constantly working on upgrading the software.

Node.js is a good example of such software as new versions come out regularly. Users can choose whether they want to work with the LTS (the long-term supported version) or the latest version with the newest features.

This article should have helped you update Node.js on any operating system.
