pip换源

设为默认清华源

升级 pip 到最新的版本 (>=10.0.0) 后进行配置：

1
2
python -m pip install --upgrade pip
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

如果您到 pip 默认源的网络连接较差，临时使用本镜像站来升级 pip：

1
python -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pip

提前说：如果配置镜像源后报 HTTP 错误，只需要将源链接中的 https://… 中的 s 删掉就行 清华源
