方法一(全局设置)
先执行：
pip config set global.proxy http://mirrors.aliyun.com/pypi/simple/
执行完后出现一个文件，并给出了地址：
C:\Users\Administrator\AppData\Roaming\pip\pip.ini
打开文件，再替换里面的内容：
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host = mirrors.aliyun.com
方法二（临时）
将【yourpackage 】替换成你需要的依赖
pip install yourpackage -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
建议使用第一种。我就是第一种方式解决的
