无法使用python pip安装/卸载软件包

Question

When I tried to install or uninstall packages using pip(with or without using sudo), I am getting Exception.

Exception:
Traceback (most recent call last):

My OS is MacOS Sierra. I have tried to uninstall and install pip, but the problem still exists. Please help.

Ok, your questions seems to be missing some vital information for it does not state the exact command you use to try and install a python module using pip. Please always try to provide a minimal, complete, and verifiable example .

If I'd have to take a guess by the error-code however, I would guess you are facing a permission/rights issue rather then a pip-issue. I see 2 clues that make me suspect such a thing. For 1: [Errno 1] usually means there is a permission error and 2: you mention in your comments that you installed packages using --user , but did you use that when trying to uninstall them as well?
