python更改下载源地址
python默认的pip源在国外，如果下载比较大的第三方库时可能会非常非常慢，甚至会报错，所以为了有一个更加友好的python使用体验，建议为python的pip换一下源。
临时使用pip源
在使用pip时候，后面加上参数-i 镜像地址，例如：
pip3 install pygame -i http://mirrors.aliyun.com/pypi/simple/
永久修改：
pip config set global.index-url http://mirrors.aliyun.com/pypi/simple/
豆瓣・・・・・・・・・・・・・・・http://pypi.douban.com/
华中理工大学・・・・・・・・http://pypi.hustunique.com/
山东理工大学・・・・・・・・http://pypi.sdutlinux.org/
中国科学技术大学・・・・http://pypi.mirrors.ustc.edu.cn/
阿里云・・・・・・・・・・・・・http://mirrors.aliyun.com/pypi/simple/
[root@localhost bin]# ./pip config set global.index-url http://mirrors.aliyun.com/pypi/simple/
Writing to /root/.config/pip/pip.conf
