I got this error when I tried running pip:
from pip import main ImportError: cannot import name 'main'
I had installed pip from Ubuntu repositories using this command:
$ sudo apt install python-pip
However, I had previously used a pip from Anaconda on this computer. Though I had uninstalled it, it looked like it had left some files that were affecting how the Ubuntu pip worked.
I found the
~/.local/lib directories that Anaconda pip had created and deleted those directories. Ubuntu pip worked fine after that.
Tried with: Ubuntu 16.04
