I could install with psycopg2 version >= 2.8.0
but with 2.7.x , pip install will generate those error messages.

is that mean psycopg2 2.7.x can not work with python 3.8 in ubuntu 20.04 ?

Package failed to install error while installing package

Once you open the file, open your shell in the directory where the file is located (e.g. C:UsersExampleDownloads ) and install it using pip :

1. Open the directory that contains the file in Explorer.
2. Press Shift and right-click in Explorer.

1. Click on «Open PowerShell window here».
2. Run the following command.

Make sure to specify the name of the .whl file correctly as your Python version and the name of the package will likely be different.

If that didn’t help and your error message contains something like: «error: Microsoft Visual C++ 14.0 or greater is required. Get it with «Microsoft C++ Build Tools»: https://visualstudio.microsoft.com/visual-cpp-build-tools/», download Microsoft Build tools and check the «Desktop development with C++ checkbox when installing.

Check if your Python version is supported by the package #

The «error: legacy-install-failure» is sometimes caused when the package you are trying to install doesn’t have available wheels for your version of Python.

You can check your Python version with the python —version command.

You can check if a package has wheels available for a specific Python version in the Download files section of the package’s pypi page.

If the .whl files are not available for your version of Python, you can download an older version.

You can download a specific Python version that is supported by the package if the package doesn’t support the latest Python version.

Different versions are available in the «Looking for a specific release» table.

Make sure to tick the following options if you get prompted:

• Install launcher for all users (recommended)
• Add Python to PATH (this adds Python to your PATH environment variable)

Create a virtual environment #

To solve the «error: legacy-install-failure»:

1. Create a virtual environment.
2. Activate the virtual environment.
3. Run the pip install command with the virtual environment active.

If the python3 -m venv venv command doesn’t work, try the following 2 commands:

• python -m venv venv
• py -m venv venv

Make sure to use the correct command to activate your virtual environment depending on your operating system and your shell.

Your virtual environment will use the version of Python that was used to create it.

Try running pip install in verbose mode #

If none of the suggestions helped, try running the pip install command in verbose mode.

The -v option stands for verbose mode and can be used up to 3 times.

When the pip install command is run in verbose mode, the command shows more output and how the error occurred.

Conclusion #

To solve the «Error: legacy-install-failure»:

1. Upgrade your versions of pip , setuptools and wheel before running pip install .
2. Check if your Python version is supported by the package.
3. On Windows, download and install the package from unofficial binaries.
4. Try to install the package with the —pre option.

Encountered error while trying to install package

28.07.2022 698 Просмотры

Я хочу установить пакет gensim python через pip install gensim.

Но возникает эта ошибка, и я не знаю, что мне делать, чтобы решить ее.

Если вам не удалось установить плагины,
вы можете скачать его из других репозиториев, например, из этого: репозиторий зависит от версии python и системы.

например: для windows 11(x64) и python 3.10 вы должны взять этот файл: gensim-4.1.2-cp310-cp310-win_amd64.whl

Error while installing packages

Я использую Ubuntu 12.04. Я столкнулся с ошибкой при установке любого пакета с помощью apt-get. Я пробовал шаги, приведенные на различных форумах, но не смог решить проблему. Например, если я устанавливаю kcachegrind, код ошибки следующий:

[Я заменил http:// на http// только для того, чтобы избежать ссылок при размещении вопроса. Поэтому, пожалуйста, читайте http// как http:// в сегментах кода].

Попробуйте выполнить следующие команды,

sudo dpkg -P mysql-client-5.1
sudo apt-get install -f

В ошибке написано что для компиляции пакета нужно установить Microsoft C++ Build Tools версии 14.2 или выше, а также приведена ссылка где их можно скачать: https://visualstudio.microsoft.com/visual-cpp-build-tools/.

Как исправить ошибку Encountered error while trying to install package

Мир программирования полон испытаний, которые нередко пугают новичков. Вне зависимости от своего стажа, программисты сталкиваются с различными багами, глюками, сбоями и прочими ошибками, на исправление которых может уйти как несколько минут, так и целый день. Например, Python-разработчики часто сталкиваются с ошибкой «Encountered error while trying to install package». Расскажем о том, что это за ошибка и что делать при ее возникновении.

Что это за ошибка

Вообще, чаще всего пользователи читают только половину вывода интерпретатора (а порой и вовсе только ее название), не обращая внимания на ее описание и результаты трассировки, которые указаны выше. Для того чтобы разобраться в проблеме, попробуем дословно перевести ее на русский.

«Обнаружена ошибка при попытке установить пакет» – именно так звучит ошибка. Она возникает только в тех случаях, когда пользователь хочет установить сторонний пакет Python с помощью пакетного менеджера Pip. Чаще всего проблема связана с нехваткой необходимого модуля или пакета. Название отсутствующего компонента указывается в результатах трассировки.

Как исправить

Многие устанавливаемые пакеты зависят от служебного компонента, который называется «Microsoft C++ Build Tools» (инструменты сборки Microsoft C++). В первую очередь попробуйте установить его. Алгоритм действий:

• Нажмите на кнопку «Загрузить Build Tools».

• Дождитесь завершения загрузки и запустите установщик.
• Укажите путь для сохранения компонента.

• Дождитесь завершения установки.

После этих махинаций снова попробуйте установить проблемный компонент. Если ничего не получилось, то значит проблема в нехватке другого компонента. Внимательно ознакомьтесь с выводом интерпретатора, в котором будет указан недостающий файл.

How To Solve Error: legacy-install-failure?

Python provides you with a package installer called ‘pip.’ ‘Pip’ allows you to write a line of code to install packages and manage them. Although sometimes, when you are installing some packages, you might get an ‘error: legacy-install-failure.’ For example, if you are trying to install the gensim package in python. To know more about ‘pip’ check out this post.

Solving ‘ Error: legacy-install-failure’

In this article, we will discuss how we can solve this error.

Solve error: legacy-install-failure For Gensim

Pip is a package installer and manager, and the wheel is a way that pip prefers to install packages because the wheel allows fast and efficient installations and are smaller in comparison to eggs. Hence upgrading wheels might also solve the problem of ‘error: legacy-install-failure.’ The setuptools enhance the over-installation by enhancing the python standard library distribution utilities. Therefore if you update these modules, it might solve your error because this error can also arise if one of these modules is not up-to-date. Let us see how we can upgrade these modules.

• First, update your pip installer as shown below.

• Then upgrade your wheel by using:

• Then finally upgrade the setuptools.

• And then again try to install the package which was throwing error in the first place.

Solve error: legacy-install-failure In Pandas

Pandas is an open-source library in python which allows users to perform high-level data manipulation. It is one of the most important libraries in python in the sense of data structure programming and data analysis because it provides flexible, fast and expressive data structures. However, sometimes when you try to install this library using pip, you can get an ‘error: legacy-install-failure,’ which can prevent us from using this very important library. Let us see how we can solve this error in python.

To solve this problem, you need to install ‘pipwin’ because it may happen that the ‘pandas’ wheel might not support the python version you are working on; therefore, first, install ‘pipwin’.

And further, when you install ‘pipwin,’ install ‘pandas’ using ‘pipwin.’

This should probably solve the ‘error: legacy-install-failure’ and allow you to install the pandas library and use it.

Solve error: legacy-install-failure For Basemap

Basemap is a tool in python that provides you to create maps in a very easy and simple way. It is an extension of the ‘ matplotlib ‘ library; therefore, it contains all the features for carrying out data visualization. It further adds geographical projections and some other additional data sets in order to enable plotting coastlines, countries, states, boundaries and etc., directly from the library. Similarly, when you try to install this library through ‘pip,’ you might face a Solve ‘ error: legacy-install-failure’. We will discuss how we can solve this error for the basemap library.

Solving For Windows Operating System

If you are using Windows operating system and encounter this error you need to follow some steps. The steps are as given below:

gohlke/pythonlibs/#basemap

Doing this should solve the ‘error: legacy-install-failure’ error.

Solving For MAC Operating System

If you are using MAC Operating System and encounter this error, you need to follow some steps. The steps are as given below:

• First, make sure you install all the packages as shown below:

• Then you have to add GEOS_DIR = “/ user / local / Cellar / geos / 3.10.2 /” to your .bash profile and reload it via: source

/.bash_profile. You can do that by :

• Further, go to the basemap directory from the path: basemap/packages/ basemap. And finally, run the install code from that directory.

This should solve the ‘error: legacy-install-failure’ error.

Solving For Google Colab

To solve this error in google colab, you need to run the commands given below, and doing that should solve the ‘error: legacy-install-failure’ error.

Solve error: legacy-install-failure For MySQL

MySQL provides services for handling and managing databases. When you connect your python application to an active server, you can manage all your database using MySQL. Although when installing using an ‘Error: legacy-install-failure’ error might occur. It can display something like this.

To solve this following error, you will need to follow the steps given below:

• First, run the commands given below

• Further, make some changes in the settings file if you are using some framework like Django or any other. To make this change run these commands.

Further, install all other dependencies in the env/lib/python3.8/site-packages/django/db/backends/mysql/base.py directory. These dependencies can be installed like:

• Now try to install MySQL again, as following these steps should solve the error.

Solve error: legacy-install-failure For Wxpython

Wxpython is a cross-platform Graphical User Interface toolkit for python language. It enables the users to program independent and robust code, which provides a very high graphical user interface very easily and quite simply. This library, like many other libraries, is open source. Although sometimes, while installing ‘wxPython,’ you might face an ‘error: legacy-install-failure’ error.
