在windows计算机上运行pip安装。由于web代理而获取证书错误

Question

我已经准备好在公司网络中使用Python的环境。我认为，由于我们在防火墙上使用SSL拦截，python不信任安装期间提供的证书。我们使用Palo Alto防火墙，如果您检查任何SSL网站，您将看到防火墙是所有SSL网站的签名证书。这是一个windows工作站，CA证书在windows证书存储中受信任。当我运行命令时

python-mpip安装——升级pip

我得到这个错误

我不确定结尾是否有标签。我看到了一个类似的问题，但我认为这与存储库url使用的特定证书无关。

感谢您的帮助。非常感谢。

由于您使用的是代理，pip无法访问python包索引。如果您的公司使用专用的pypi克隆，则必须更改pip。ini文件位于C:\Users\

[global]
index-url = your company url
cert = location of your certs (ask IT
[search]
index = your company url

这个url通常是某种人工制品。
