method one

1. After we enter pycharm, click File—>Settings in the upper left corner

2. Click Project: Proton Interpreter under the project name, and then click the + sign below.

3. Click Manage Repositions below

4. Click the default path, click the - sign to delete it, and then add one of the following mirror sources . I use Ali 's and it's still very fast. Friends can try each one, just find the one that is quicker.

Note that the new version of ubuntu requires the use of https sources.

Method Two

1. We open my computer and enter the following path C:\Users\SHI\AppData\Roaming, where SHI is my username,

2. In the Roaming folder, create a new folder named pip, if there is, do not need to create a new one

3. Create a new text file.txt

4. Then change the name and suffix to pip.ini If there is, do not create a new one

5. Right-click to edit the original Delete the content and modify it to the following content. For the convenience of everyone to paste, I will copy mine directly. It is convenient for everyone to use Ctrl+c and Ctrl+v.
