CentOS installation pip tutorial: Quickly obtain the Python package management tool, you need specific code examples

In the process of using Python for development, you often encounter the installation of various Requirements for third-party libraries. As a Python package management tool, pip can help us obtain and install Python packages quickly and easily. This article will introduce how to install pip in CentOS system and provide specific code examples to help readers easily complete the installation process.

1. Update system

Before installing pip, we first need to ensure that our system is up to date. You can update the system by executing the following command:

sudo yum update

This command will check and update all software packages in the system to ensure that the system is up to date.

2. Install pip

CentOS system provides an additional software source called epel-release, which contains many commonly used third-party software packages. We can install epel-release through the following command:

sudo yum install epel-release

After the installation is completed, we can use the yum command to install pip:

sudo yum install python-pip

The above command will automatically download and install pip and its dependent packages. After the installation is completed, we can verify whether pip is successfully installed by using the following command:

pip --version

If the version number of pip is displayed correctly, it means that pip has been successfully installed.

3. Configure pip source

By default, pip will use the official software source to obtain software packages. However, due to the particularity of domestic networks, downloading speeds from official sources are sometimes slower. Therefore, we can configure the source of pip to be a domestic mirror to improve download speed.

First, back up the pip configuration file:

cp ~/.pip/pip.conf ~/.pip/pip.conf.bak

Then, edit the pip configuration file:

vi ~/.pip/pip.conf

Add the following content to the open file:

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

Save and exit the editor.

So far, we have successfully installed pip and configured the source as a domestic mirror. The following is an example showing how to use pip to install a third-party library named requests:

pip install requests

The above command will automatically download and install the requests library and its dependent packages from the specified source. Once installed, we can use the library in Python scripts.

Summary: This article introduces the steps to install pip in CentOS system and provides specific code examples. By following the above steps, readers can easily install pip on their own machines and use pip to manage Python packages. In daily development, pip will become an indispensable part of the tool, helping us obtain and install third-party libraries more conveniently.
