运行pip安装 - 在Windows机器上 . 由于Web代理而导致出现Cert错误

我正准备在我的公司网络中使用Python . 我相信由于我们在防火墙上使用SSL拦截，python不信任安装期间出现的证书 . 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证书库中受信任 . 当我运行命令

python -m pip install --upgrade pip

我收到这个错误

PS U:\code> python -m pip install --upgrade pip

我不确定最后是否有标签 . 我看到了类似的问题，但我认为它与存储库URL使用的特定证书无关 .
