How to switch pip installation sources in Python and how to switch pip in python

Pip is a tool for installing python packages. It provides the installation package to list installed packages, upgrade packages, and uninstall packages.

Pip is a replacement of easy_install and provides the same search Package function as easy_install. Therefore, you can use the package installed by easy_install or pip for installation.

> Mkdir. pip

> Ls ~ /. Pip

3. Edit Source

Sudo vi ~ /. Pip/pip. conf

[global] index-url = http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com 

Solution 2:

pip install turtle --trusted-host mirrors.aliyun.com 

Iv. Test comparison
