How to upgrade pip

You can upgrade pip and manually install the latest version of pip by using pip's own upgrade command, the operating system's package management tool. Detailed introduction: 1. Use pip's own upgrade command, use pip install --upgrade pip command to upgrade pip to the latest version; 2. Use the operating system's package management tool to upgrade pip. You can use apt on Ubuntu and CentOS. yum, package management tools such as brew can be used on MacOS to install and upgrade software, etc.

The operating system for this tutorial: Windows 10 system, Python version 3.11.4, DELL G3 computer.

Upgrading pip is to ensure that we are using the latest version of the Python package management tool, so that we can get better performance and functionality. Before upgrading pip, we need to understand the currently installed pip version and then choose the appropriate upgrade method.

Below I will introduce some common methods to upgrade pip:

Method 1: Use pip’s own upgrade command

If we have already installed it pip, you can directly use the following command to upgrade pip to the latest version:

pip install --upgrade pip

The function of this command is to use the currently installed pip to install the latest version of pip. After the command is executed, we will have the latest version of pip.

Method 2: Use the package management tool of the operating system to upgrade pip

For some operating systems, for example, apt can be used on Ubuntu, yum can be used on CentOS, and MacOS You can use package management tools such as brew to install and upgrade software. We can use the system package management tool to upgrade pip with the following command:

For Ubuntu:

sudo apt update
sudo apt install python3-pip

For CentOS:

sudo yum update
sudo yum install epel-release
sudo yum install python-pip

For MacOS:

brew upgrade python

These commands will upgrade the pip that comes with the system to the latest version, and ensure that pip is installed and upgraded correctly.

Method 3: Manually install the latest version of pip

If we still cannot successfully upgrade pip through the above method, we can try to manually download and install the latest version of pip. First, we need to download the latest version of the pip installation package from https://pypi.org/project/pip/#files, and then install it manually through the following command:

python get-pip.py

This command will run the downloaded installation package, install the latest version of pip. At the same time, we can use the command pip --version to confirm that we have the latest version of pip installed. But it is worth noting that the method of using the command line is the same for Windows users; but the path location may be different.

Upgrading pip is a good way to ensure that we can get new features and performance optimizations, and it can also solve some bugs and security vulnerabilities in older versions of pip. Need to make sure we are using the latest version pip, because older versions of pip may cause unnecessary trouble to our code and projects. Of course, before all of this, let's make sure to back up all project files and virtual environments.
