Как установить Pip на Debian 9

Pip — это система управления пакетами, которая упрощает установку и управление пакетами программного обеспечения, написанными на Python, такими как те, которые находятся в индексе пакетов Python (PyPI) .

Это руководство проведет вас через установку Python Pip в Debian 9 и научит, как устанавливать пакеты Python и управлять ими с помощью pip.

Подготовка

Прежде чем продолжить это руководство, убедитесь, что вы вошли в систему как пользователь с привилегиями sudo .

Стоит отметить, что если вы хотите установить модуль python глобально, вы должны предпочесть установить его как пакет с помощью менеджера apt . Используйте pip для глобальной установки модулей Python, только если пакет недоступен.

Обычно вы используете pip только внутри виртуальной среды. Virtual Environment Python позволяет устанавливать модули Python в изолированном месте для конкретного проекта, а не глобально. Таким образом, вам не нужно беспокоиться о влиянии на другие проекты Python.

В следующих разделах мы покажем вам, как установить pip для Python 2 pip и Python 3 pip3 с помощью диспетчера пакетов apt .

Установите Pip для Python 2

Выполните следующие действия, чтобы установить Pip для Python 2 в вашей системе Debian:

Начните с обновления индекса пакетов:

sudo apt install python-pip

pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

Установить pip для Python 3

Выполните следующие действия, чтобы установить Pip для Python 3 в Debian:

Сначала обновите список пакетов:

sudo apt install python3-pip

pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.5)

Использование пункта

В этом разделе мы покажем вам несколько полезных базовых команд pip. С помощью pip мы можем устанавливать пакеты из PyPI, системы контроля версий, локальных проектов и из файлов распространения, но в большинстве случаев вы будете устанавливать пакеты из PyPI.

Допустим, мы хотим установить пакет с именем croniter , мы можем сделать это, выполнив следующую команду:

Чтобы удалить пакет, выполните:

pip uninstall package_name

Для поиска пакетов из PyPI:

Installation#

If your Python environment does not have pip installed, there are 2 mechanisms to install pip supported directly by pip’s maintainers:

ensurepip #

Python comes with an ensurepip module [ 1 ] , which can install pip in a Python environment.

$ python -m ensurepip --upgrade

$ python -m ensurepip --upgrade

More details about how ensurepip works and how it can be used, is available in the standard library documentation.

get-pip.py #

This is a Python script that uses some bootstrapping logic to install pip.

• Download the script, from https://bootstrap.pypa.io/get-pip.py.
• Open a terminal/command prompt, cd to the folder containing the get-pip.py file and run:

More details about this script can be found in pypa/get-pip’s README.

Standalone zip application#

The zip application is currently experimental. We test that pip runs correctly in this form, but it is possible that there could be issues in some situations. We will accept bug reports in such cases, but for now the zip application should not be used in production environments.

In addition to installing pip in your environment, pip is available as a standalone zip application. This can be downloaded from https://bootstrap.pypa.io/pip/pip.pyz. There are also zip applications for specific pip versions, named pip-X.Y.Z.pyz .

The zip application can be run using any supported version of Python:

then the currently active Python interpreter will be used.

Alternative Methods#

Depending on how you installed Python, there might be other mechanisms available to you for installing pip such as using Linux package managers .

These mechanisms are provided by redistributors of pip, who may have modified pip to change its behaviour. This has been a frequent source of user confusion, since it causes a mismatch between documented behaviour in this documentation and how pip works after those modifications.

If you face issues when using Python and pip installed using these mechanisms, it is recommended to request for support from the relevant provider (eg: Linux distro community, cloud provider support channels, etc).

Upgrading pip #

Upgrade your pip by running:

$ python -m pip install --upgrade pip

$ python -m pip install --upgrade pip

C:> py -m pip install --upgrade pip

Compatibility#

The current version of pip works on:

pip is tested to work on the latest patch version of the Python interpreter, for each of the minor versions listed above. Previous patch versions are supported on a best effort approach.

Other operating systems and Python versions are not supported by pip’s maintainers.

Users who are on unsupported platforms should be aware that if they hit issues, they may have to resolve them for themselves. If they received pip from a source which provides support for their platform, they should request pip support from that source.

The ensurepip module was added to the Python standard library in Python 3.4.

Install Python PIP Debian 11

“Pip is the most popular package installer for Python. You may manage and install new python-based software packages using PIP, a Python command-line package manager. However, users can install its dependencies and do package searches in the Python packages index using this tool. Most Linux operating systems do not come pre-installed with the Python pip tools. Fortunately, you can manually install the python-pip tool on Debian and other Linux distributions.

Today, we will show in this article how to install python-pip packages on the Debian 11 bullseye distribution through the command line application. Almost all steps are similar, so by following these guidelines, you can install python-pip on Ubuntu and its derivates.”

How to Install Python Pip on Debian 11 Bullseye Distribution?

How to Use Python Pip in Linux?

We will also explore the use of pip in this article. Using pip, the user can install python packages from PyPI, local projects, version control, and other project distributions. Usually, the pip would be used inside the virtual environment. Python virtual environment allows you to install python packages inside an isolated space without disturbing the other python project modules.

Let’s discuss some useful pip commands.

With pip, you can list all packages as follows:

You can search for a package through pip by using the following command:
