How to check pip version

There are four ways to check the pip version: "pip --version command", "pip show command", "pip list command" and "view in Python code": 1. "pip --version", output The current pip version and the path information of Python; 2. "pip show package_name" displays the detailed information of the package, including the currently installed version number, etc.

1. Use the pip --version command

The most basic method is to use the pip --version command to view the current pip version.

pip --version

After the command is executed, the current pip version and the path information of Python will be output.

In addition to checking the global version, we can also check the pip version in a certain Python virtual environment.

python -m venv myenv
source myenv/bin/activate
pip --version

Execute the pip --version command in the virtual environment myenv, and the pip version in the virtual environment will be output.

2. Use the pip show command

The pip show command can obtain the detailed information of an installation package. Many times we need to check the version number of a certain package. We can obtain the corresponding information through this command. .

pip show package_name

Using the above command will display the detailed information of the package, including the currently installed version number.

3. Use the pip list command

The pip list command can list all installed Python packages and their versions. If you only focus on the pip version, you can use grep to filter the results. Only List information about pip and its dependent packages.

pip list | grep ^pip

The above command will only output information about pip and its dependencies, including version number, installation path, etc.

4. Check the pip version in Python code

Using Python code to obtain the pip version is also an effective way.

import pip
print(pip.__version__)

Introduce the pip library into the Python code, and then use the pip.__version__ attribute to print the version number.
