python - Pip 错误，OSError Errno 22 参数无效

Question

使用pip搜索或安装包时，出现如下错误:

pip3 search validate
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProtocolError('Connection aborted.', OSError(22, 'Invalid argument'))': /pypi
Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by 'ProtocolError('Connection aborted.', OSError(22, 'Invalid argument'))': /pypi

pip 版本:来自/usr/local/lib/python3.6/site-packages (python 3.6) 的 pip 9.0.1
Python版本:3.6.3
操作系统:macOS High Sierra 10.13

我试过重新安装 python 和 pip。我不相信我在使用任何代理，它可能不是防火墙(我可以 ping/dig pypi.python.org)。

经过一些额外的挖掘，运行 curl pypi.python.org 发出相同的错误:curl: (55) getpeername() failed with errno 22: Invalid argument。

就我而言，这是 macOS High Sierra 上 IPv6 的问题。要解决此问题，请打开您的网络首选项，从列表中选择 Wi-Fi，然后单击“高级...”。单击 TCP/IP 选项卡，然后将配置 IPv6 更改为仅本地链接。
