However, when accessing foreign pip sources in China, you often encounter problems of slow speed or even inability to connect. Therefore, we can improve download speed and stability by changing the pip source to a domestic mirror source. This article will introduce you how to change the pip source with specific code examples.

pip config set global.index-url https://pypi.douban.com/simple

This command will change the pip source to Douban source. If you want to change the source to another mirror source, just replace the link with the address of the corresponding source.

2. To verify whether the changes take effect, run the following command:

pip config list

Check the contents of the pip configuration file again and confirm whether global.index-url has been modified to https:// pypi.douban.com/simple.

4. Restore the original pip source
If you want to restore the original pip source, you can follow the steps below.

1. Open a terminal or command prompt and run the following command:

pip config unset global.index-url

This command will delete the previously set pip source configuration.

2. To verify whether the recovery is effective, run the following command:

pip config list

Check the contents of the pip configuration file again to confirm whether global.index-url has been deleted.

Conclusion:
By changing the pip source to a domestic mirror source, we can greatly improve the download speed and stability of the package and improve the problem of domestic access to foreign pip sources. This article takes replacing Douban source as an example to show you the specific steps on how to change the pip source. I hope this article is helpful to you, thank you for reading.
