"pip install . "not working on Linux

[tomsnick]

I think I successfully loaded ccgains on my Linux machine but cannot get pip to work:
tomf@tomVaio:/ccgains/ccgains$ pip install .
Traceback (most recent call last):
File "/usr/bin/pip", line 9, in
from pip import main
ImportError: cannot import name main
I get the same error with
tomf@tomVaio:/ccgains/ccgains$ pip install --user .
as well as in one directory up:
tomf@tomVaio:/ccgains$ pip install --user .
To help figure out the problem here are the directory contents:
tomf@tomVaio:/ccgains$ dir
ccgains COPYING data examples README.md setup.py
contributors.txt COPYING.LESSER docs MANIFEST.in run_tests.sh tests
tomf@tomVaio:/ccgains/ccgains$ dir
bags.py historic_data.py relations.py templates
binance_util.py init.py reports.py trades.py
I removed the ccgains directories and "git cloned" again but got the same error message with pip. There are no obvious errors that I can see during "git clone" but here is confirmation, in case that helps determine the problem:
tomf@tomVaio:$ git clone https://github.com/probstj/ccgains.git

This is actually a problem with python/pip on certain linux distributions. There's more details on this issue thread that might help you get it working. There's a few different things to try depending on your distro, specific python version, whether pip has been modified since installing by your package manager, etc.

Thank you.
