当我尝试使用pip安装autopep8时，为什么会出现此错误？

我尝试了'pip install autopep8‘，然后我尝试了'pip3 install --upgrade autopep8’，我得到了同样的错误。这似乎是一个连接问题，但我连接到互联网，可以下载和上传的东西。‘ProxyError’(‘无法连接到代理服务器’有什么问题？我该如何处理这件事？我需要做什么来配置我的代理设置？

Answer 1

您可以将代理指定为pip install的参数：

pip install <package> --proxy http://your.proxy.net:8080/

如果您还遇到ssl证书错误(在企业环境中也很常见)，您也可以将pypi启用为受信任的主机：

pip install <package> --proxy http://your.proxy.net:8080/ --trusted-host pypi.python.org

通过这样做，希望你能解决你的问题。
