python如何设置清华镜像源

在cmd窗口中输入

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple 库名

或：

pip install 库名 -i https://pypi.tuna.tsinghua.edu.cn/simple

原始网站：https://pypi.python.org/simple

 永久设置方法，同样在cmd窗口中输入：

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

附：

豆瓣镜像源：

pip install SnowNLP -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

若出现报错则可以参考以下方法:

C:\WINDOWS\system32>pip install pip -U Script file 'D:\Software\Anaconda3\Scripts\pip-script.py' is not present.

C:\WINDOWS\system32>pip config set global.index-url Simple Index Script file 'D:\Software\Anaconda3\Scripts\pip-script.py' is not present.

python -m ensurepip --default-pip
