python3修改pip源

1、修改默认源

查看当前使用源
创建pip目录：

MacBook-Pro-2:~ root# cd /Users/huangshihui/Library/Application\ Support/
MacBook-Pro-2:~ root# mkdir pip
MacBook-Pro-2:~ root# vim pip.conf

加入以下内容，修改为清华源

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

查看当前的pip3情况

huangshihui@huangshihuideMacBook-Pro-2 pip % pip3 show pip
