我正在尝试安装包request_ntlm。 如果我尝试使用以下命令，我仍会收到SSL错误：
pip install --trusted-host pypi.python.org --proxy http://username:password@site.address:port requests_ntlm
我尝试添加--index-url=http://pypi.python.org/simple/，将可信和索引网址更改为http：/pypi.python.org,https：pypi.org，http://pypi.python.org/，http://pypi.python.org/pypi/但我最终结果相同。
包括-v会返回以下内容：
pip install --trusted-host pypi.python.org --proxy http://username@password@site.address:port -v requests_ntlm
