pip install 挂代理

挂了代理之后，pip install包时会出现：

(tool) F:\研究生工作\工具库  pip install pyperclip
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', ConnectionResetError(10054, '远程主机强迫关闭了一个现有的连接。', None, 10054, None))': /simple/pyperclip/

关闭代理即可正常安装。

当然正确姿势是在挂着代理时也能正常安装。

方法是给pip配置代理。参考：6.python设置代理和添加镜像源介绍 - 大-道-至-简 - 博客园 (cnblogs.com)

windows下在user目录下创建pip/pip.ini，写入(对于clash代理)：

[global]
proxy=http://127.0.0.1:7890

即可正常。

ps，还会出现一次的，有点奇怪。
