A brief tutorial on installing pip: steps under Linux system

Steps and code examples for installing pip on Linux system

When using Python for development under Linux, you must first set up a Python environment. However, there is no pip in the Python standard library, so you need to manually install pip yourself to conveniently install and manage the Python library.

Below, we will introduce the steps to install pip under Linux system and provide corresponding code examples.

Step 1: Check the Python version

The Python environment provides multiple versions of Python libraries, so first check the Python version in the current system to ensure that pip is installed The version is correct.

Use the following command to check the Python version:

python --version

After running the above command, the Python version installed on the current system will be displayed, for example:

Python 2.7.17

This shows that the Python version used in the current system The version is Python2.7.

Step 2: Install pip dependencies

Before installing pip, you need to install some necessary dependencies for pip. The installation method is as follows:

Debian Series:

sudo apt-get install python-pip python-dev build-essential 

CentOS Series:

sudo yum install python-pip 

Step 3: Download the pip installation package

Before installation, you must first download pip from the official website Installation package (https://pypi.org/project/pip/).

When downloading, please note that pip needs to correspond to the Python version. For example, for Python2.7 version, you should download the corresponding pip installation package.

Use the following command to download (here, take Python2.7 version as an example):

wget https://files.pythonhosted.org/packages/31/ca/08e73e6a32fcd7ff1a0468f94a1ee737c8959f278f4ef98a51933202dfec/pip-20.2.4.tar.gz#sha256=fa170b7b9d2bbf168e48bbfe2bf3bb3e18a8c884f02f53e90501b454f4d8950a

After the download is complete, use the following command to decompress:

tar -zxvf pip-20.2.4.tar.gz

Steps Four: Install pip

Use the following command to install pip:

cd pip-20.2.4 && python setup.py install

In this way, pip has been installed successfully.

Step 5: Test the pip function

After the installation is complete, use the following command to test the pip function:

pip -V

If the pip version is displayed The number indicates that pip installation was successful.

Summary

The above are the steps and code examples for installing pip under the Linux system. They are very simple and easy to master. Python is a very popular programming language, and the environment it builds is also very convenient and flexible. We hope this article can help developers who are using Linux for Python development and make them program more efficiently and conveniently. .
