我已阅读以下页面中的消息:

I have read the messages in the following pages:

• Python PIP安装抛出TypeError:不受支持的操作数类型(s)-=:重试"和"int"
• https://github.com/pypa/pip/issues/3943
• https://github.com/pypa/pip/issues/4133

• Python PIP Install throws TypeError: unsupported operand type(s) for -=: 'Retry' and 'int'

我不使用任何代理服务器或防火墙(除非您将我的路由器都视为idk).

I'm not using any proxy or firewall (unless you count my router as both, idk).

推荐答案

当我身为公司代理人时，这会发生在我身上.要解决此问题，请使用--proxy=urlOfYourProxy运行.

This happens to me when I am behind a corporate proxy. To fix that, run with --proxy=urlOfYourProxy.

例如:

pip install --proxy user:password@http://localproxy:8080
