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
