Python install whl with pip

Установка пакетов Python с помощью .whl файлов

Иногда при работе с Python возникает необходимость установить пакет, который доступен только в формате .whl (Wheel). Это бинарный формат дистрибутива, который позволяет устанавливать Python пакеты без компиляции исходного кода и не требует наличия всех библиотек, необходимых для сборки пакета.

Примером может быть ситуация, когда создается проект на Python в Windows, и для его работы требуется библиотека, доступная только в формате .whl.

Такой формат дистрибутивов поддерживается средством установки пакетов pip, начиная с версии 1.4.

Процесс установки пакетов с помощью .whl файлов

Процесс установки пакета с помощью .whl файла включает в себя несколько шагов:

1. Сначала необходимо скачать .whl файл пакета. Это можно сделать с официального сайта пакета или с других надежных источников.
2. После того, как файл скачан, его нужно установить. Это делается с помощью pip, и команда для установки выглядит следующим образом:

   pip install some-package.whl

   Здесь some-package.whl — это имя скачанного файла.

Эта команда должна быть выполнена в командной строке, и перед выполнением необходимо перейти в каталог, где расположен скачанный .whl файл.

После выполнения команды пакет будет установлен и готов к использованию.

Важно отметить, что для работы с .whl файлами необходим pip не ниже версии 1.4. Если установлена более старая версия, то ее можно обновить следующей командой:

pip install —upgrade pip

Эта команда обновит pip до последней доступной версии.

Заключение

Таким образом, установка Python пакетов с помощью .whl файлов — это простой и удобный способ добавить в проект необходимые библиотеки. Этот подход особенно полезен, когда нет возможности собрать пакет из исходного кода или когда пакет доступен только в формате .whl.

Python packages are collections of modules that provide additional functionality to Python. Installing Python packages is an essential task for Python developers, and there are various ways to install a Python package, including using a WHL file. In this tutorial, you will learn how to install a Python package with a WHL file.

Understanding WHL Files

Before we dive into the installation process, it is essential to understand what a WHL file is. A WHL file is a Python wheel file that contains a pre-built Python package. It is a binary distribution format that includes all the necessary files and metadata required to install a Python package. A WHL file is platform-specific, which means that it can only be installed on a specific platform, such as Windows, Linux, or macOS.

Prerequisites

Before we begin, make sure that you have Python installed on your system. You can download Python from the official website at https://www.python.org/downloads/. Additionally, you will need to have the pip package manager installed, which is included with Python 2.7.9 and later versions. If you have an older version of Python, you can install pip by following the instructions at https://pip.pypa.io/en/stable/installation/.

Installing a Python Package with a WHL File

To install a Python package with a WHL file, follow these steps:

• Download the WHL file for the package you want to install. You can download WHL files from various sources, including PyPI (Python Package Index) at https://pypi.org/.
• Open a command prompt or terminal window.
• Navigate to the directory where you downloaded the WHL file using the cd command. For example, if you downloaded the WHL file to the Downloads folder on a Windows system, you would use the following command:

• Once you are in the correct directory, use the pip install command to install the package. For example, if you downloaded the requests package for Windows, you would use the following command:

pip install requests-2.26.0-py2.py3-none-any.whl

• Wait for the installation process to complete. Once the installation is complete, you should see a message that says «Successfully installed [package name].»

Conclusion

In this tutorial, you learned how to install a Python package with a WHL file. You also learned what a WHL file is and the prerequisites for installing a Python package with a WHL file. By following the steps outlined in this tutorial, you can easily install Python packages with WHL files and take advantage of the pre-built packages available for Python.

How to Install a Python Package with a .whl File?

Problem Formulation: Given a file yourPackage.whl that resides in the folder C:\your\folder\ . How to install it on your Windows machine?

Background .whl Files

A .whl file (read: wheel file) is a zip archive that contains all the files necessary to run a Python application.

It’s a built-package format for Python, i.e., a zip archive with .whl suffix such as in yourPackage.whl . The purpose of a wheel is to contain all files for a PEP-compliant installation that approximately matches the on-disk format.

It allows you to migrate a Python application from one system to another in a simple and robust way.

Method 1: Powershell + pip + cd

This GIF shows you how you’d install a .whl package (e.g., downloaded from the Python Package index)—if unlike me, you’d downloaded the correct .whl file for your environment ;):

• Open your Windows command line or Powershell.
• cd into the folder where the yourPackage.whl file resides.

• Optional: Install pip on Windows. Chances are that it’s already installed—it comes with many Python distributions.
• Run the following command:

pip install yourPackage.whl

Method 2: Powershell + pip without cd

• Open your Windows command line or Powershell.
• Optional: Install pip on Windows. Chances are that it’s already installed—it comes with many Python distributions.
• Run the following command:

pip install C:\your\folder\yourPackage.whl

Method 3: Powershell + pip + wheel

• Open the Powershell or command line in Windows
• Upgrade pip to ensure that wheel is supported—which it is only for the newer versions of pip :

pip install --use-wheel --no-index --find-links=C:\your\folder\ yourPackage

Troubleshooting

If you experience problems with the installation, you may want to go over the following list with possible fixes, in this order:

• Open the command line or Powershell as an administrator by right-clicking on the program symbol and select “Open as administrator”:

pip3 install C:\your\folder\yourPackage.whl

python -m pip install some-package.whl
