pip import error: cannot import name main after installing pipenv

[jcbridwe]

Environment

• pip version:2.7
• Python version: 2.7
• OS: Windows 10

Description

I am trying to use pipenv as well as pip and having some issues. I installed pipenv using pip. I installed pipenv using pip. Then I went back and tried to run pip -v and got the following: ImportError: cannot import name main. I have seen this question answered for Linux and Mac, but I cannot use sudo or which commands; I am on Windows 10 using the CMD console. In my scripts folder, I see pip, pip2.7, and pip2. I cannot remember which one was my system pip. I know I need to maybe uninstall and reinstall (I have already tried to upgrade, but of course, without pip running you can't upgrade pip). I don't want to make more of a mess, so I wanted to ask how to resolve this in the CMD console on Windows.

Expected behavior

$pip -v #should return version

How to Reproduce

$pip install --user pipenv

1. Get package from '...'
2. Then run '$pip -v'
3. An error occurs.
   ImportError: cannot import name main.

Output

$pip install --user pipenv
$pip -v

Traceback (most recent call last):

Try using python -m pip instead, to upgrade/reinstall pip.
