Question

我正在准备一个可以在公司网络中使用Python的环境。我相信由于我们在防火墙上使用SSL拦截，因此python不信任安装过程中提供的证书。我们使用Palo Alto防火墙，如果您检查任何SSL网站，都会看到该防火墙是所有SSL网站的签名证书。这是Windows工作站，Windows证书存储区中信任CA证书。当我运行命令

python -m pip install --upgrade pip

我收到此错误

PS U:\code> python -m pip install --upgrade pip
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1051)'))': /simple/pip/

Requirement already up-to-date: pip in c:\program files (x86)\python37-32\lib\site-packages (10.0.1)

我不确定最后是否要添加标签。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。

感谢您的帮助。谢谢！

您位于代理之后，因此pip无法到达python包索引。如果您的公司经营专用的pypi克隆，则必须更改位于pip.ini的{{1}}文件。如果尚不存在，请使用以下信息：

C:\Users\<you>\AppData\Roaming\pip\pip.ini

此url通常是某种人工产物。

在Windows机器上运行pip install-由于Web代理而导致证书错误
