2.更换豆瓣pip
创建文件夹
mkdir ~/.pip
cd ~/.pip/
编辑配置文件
vim pip.conf
[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host=pypi.douban.com
安装pip3
pip install python3-pip
安装django速度25MB/s
pip3 install django
也可以每次使用单独的pip源
pip install pygame -i http://pypi.douban.com/simple
pip install pygame -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
