python request及pip命令挂代理后报错ValueE

1先挂上代理

2获得本机代理端口

C:\Users\Administrator>python
Python 3.8.5 (default, Sep  3 2020, 21:29:08) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

Warning:

>>> from urllib.request import getproxies
>>> getproxies()
{'https': 'http://127.0.0.1:11000', 'http': 'http://127.0.0.1:11000'}
此处获得代理端口为11000

3创建环境变量

HTTP_PROXY: http://127.0.0.1:11000
HTTPS_PROXY: http://127.0.0.1:11000

4重启命令提示行，在挂代理的情况下使用pip验证成功
