当虚拟专用网打开时，pip安装提升ValueError("check_hostname需要server_hostname")
提问于 2021-06-03 14:49:01
pip install <package>给出了异常。
raise ValueError("check_hostname requires server_hostname")
ValueError: check_hostname requires server_hostname当VPN打开时，比方说。我唯一的选择是VPN。我关不掉它。如何解决这个问题。Pip版本pip 21.1.1 Python 3.9.5 Conda版本conda 4.10.1
这是一个完整的例外。

您应该尝试使用--proxy参数执行pip，如下所示：
pip --proxy <proxy> install <module>或者，您可以尝试设置环境变量，如https://pip.pypa.io/en/stable/user_guide/?highlight=proxy#using-a-proxy-server所述
然而，使用VPN应该不会提示这种问题，可能它没有配置好，因此，所有的流量都不会通过它。首先检查您的0.0.0.0 IP路由是否指向vpn。

如果您使用VPN尝试断开它，它将解决问题。VPN更改代理服务器设置。

对我来说，唯一的解决方案是通过whl升级pip。
下载最新的whl，然后pip从whl安装pip升级(pip-21.2.4-py3-none any.whl)。
一旦我升级了PIP，那么PIP就可以按预期安装了。
根据请求从评论中复制更多详细信息。
转到pypi.org并搜索pip.py (pypi.org/ search /?q=pip.py&o=)。将文件下载到本地计算机(pip-21.2.4-py3-none any.whl)。然后，在提示符下输入"pip install“。它修好了我的。希望它也能帮到你！
