Speed Up Python Package Installs with Chinese Mirrors: Quick Setup Guide

When installing Python packages, you may encounter long waits or timeout errors. Using domestic mirror sites can dramatically speed up the process.

1. Popular Chinese mirror URLs

https://pypi.douban.com/simple/       # Douban
http://mirrors.aliyun.com/pypi/simple/ # Alibaba Cloud
http://pypi.hustunique.com/simple/   # HUST
http://pypi.sdutlinux.org/simple/   # Shandong University of Technology
http://pypi.mirrors.ustc.edu.cn/simple/ # USTC
https://pypi.tuna.tsinghua.edu.cn/simple # Tsinghua

2. Install a package temporarily from a mirror

# Add "-i" or "--index-url" parameter
pip install package_name -i https://pypi.douban.com/simple

3. Set a permanent default mirror on Windows

Create a pip folder in your user directory (e.g., C:\Users\YourName\pip) and add a pip.ini file with the following content:

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = mirrors.aliyun.com

4. Set a permanent default mirror on Linux

Edit or create ~/.pip/pip.conf (create the .pip directory if it does not exist) and add:

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = mirrors.aliyun.com
