When searching for or install packages with pip, I get the following error:
pip3 search validate

Pip version: pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)
Python version: 3.6.3
OS: macOS High Sierra 10.13
I've tried reinstalling python and pip. I don't believe I'm using any proxies, and it's probably not firewall (I can ping/dig pypi.python.org).
After some additional digging, running curl pypi.python.org emits the same error: curl: (55) getpeername() failed with errno 22: Invalid argument.
回答1:
In my case, this was an issue with IPv6 on macOS High Sierra. To resolve, open your network preferences, select Wi-Fi from the list, and click "Advanced...". Click on the TCP/IP tab, then change Configure IPv6 to Link-local only.
