Speed Up Python Package Installs: Switch pip to a Domestic Mirror

The article introduces the problem of slow and error‑prone pip installations when packages are fetched from overseas PyPI servers and explains why switching to a domestic mirror is beneficial.

1) Domestic source list

Several Chinese mirrors replicate the official PyPI repository; five commonly used mirrors are shown in the image below.

2) How to change source

Instead of manually editing configuration files, you can use a single pip command to set the global index URL. pip config set global.index-url <source_url> For example, to use the Tsinghua University mirror, run:

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple/

The speed improvement is demonstrated in the following screenshots.

3) Summary

The guide covers two main points: a list of domestic mirrors and the permanent pip configuration command. pip config set global.index-url <source_url> Remember the command and the mirror URL you prefer, and you’ll enjoy much faster Python package installations.
