问题描述

我在无法完全控制入站/出站流量处理的环境中，在Windows 7 64位上使用Python3.x.到本周为止，我已经可以将--trusted-host pypi.python.org标志与pip一起使用，并且一切正常.本周，即使使用--trusted-host标志，我也开始收到以下错误.

I use Python 3.x on Windows 7 64 bit in an environment without full control of inbound/outbound traffic processing. Up till this week I've been able to use the --trusted-host pypi.python.org flag with pip and everything worked. This week I have started getting the following error even with the --trusted-host flag.

Could not fetch URL https://pypi.python.org/simple/pytubes/: There was a probl
em confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate
verify failed (_ssl.c:720) - skipping

鉴于本周的pypi更改，我尝试将--trusted-host标志更改为https://files.pythonhosted.org/packages/，但这似乎无济于事.

I tried changing the --trusted-host flag to https://files.pythonhosted.org/packages/ in light of the pypi change this week, but that didn't seem to help.

我还尝试下载并安装certifi，wincerstore和win32 certifi轮子，以及针对此类问题的其他stackoverflow建议，例如digistore .pem cert和pip.ini文件，但均未成功.

I also tried downloading and installing the wheels of certifi, wincerstore and win32 certifi as well as other stackoverflow suggestions for this kind of issue such as the digistore .pem cert and pip.ini file without any success.

pip安装失败并显示";连接错误:[SSL:CERTIFICATE_VERIFY_FAILED]证书验证失败(_ssl.c:598)"

最后，我尝试按照此处的说明从pip 9.0.3升级到pip 10: https ://pip.pypa.io/en/stable/installing/

Finally I tried upgrading pip to pip 10 from pip 9.0.3 following the instructions here: https://pip.pypa.io/en/stable/installing/

对于curl下载，我必须传递-k，并且运行python get-pip.py失败，并出现与pip类似的ssl错误:

For the curl download I had to pass -k in, and running python get-pip.py fails with a similar ssl error to pip:

 Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)'),)': /simple/pip/

赞赏有关下一步的建议，因为.pem文件，Python CA软件包和--trusted-host标志均无法解决问题

Appreciate any suggestions for next steps since the .pem file, Python CA packages and --trusted-host flag didn't do the trick

从以下答案中获得的带有-vvv标志的新输出.

New output with the -vvv flag in pip from an answer below.

推荐答案

最终对我有用的是添加所有属于新pypi路由的域.

What ended up working for me is to add all the domains that are part of the new pypi routing.

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org <package>

还可以在pip.ini文件中进行设置.

Which can also be setup in a pip.ini file.
