[FIXED] Pipenv-Error: ModuleNotFoundError: No module named 'pip._internal'

Issue

Today, I installed Pipenv via

pip install pipenv

As mentioned in the documentation I went to a test directory and created a new virtual environment using

pipenv shell

and tried to install a package via

pipenv install numpy

I got the following error message:

Installing numpy…
⠧
Error:  An error occurred while installing numpy!
Traceback (most recent call last):
  File "/Users/florian/.local/share/virtualenvs/test-bJfQ6Jzk/bin/pip", line 7, in <module>
    from pip._internal import main
ModuleNotFoundError: No module named 'pip._internal'

This error occurs even after reinstalling pipenv, deleting all files and recreate the environment. It also had no impact if I ran pipenv install numpy inside or outside the environment.

Python 3.6.3
Pipenv 11.10.1

Thank you in advance.

Solution

After trying around for a while, I fully reinstalled pip. This solved the problem and everything is working now as expected.

Before providing the two commands, which solved the problem, I want to specify some things:

• I'm on MacOS
• python stands for python3 (added an alias for that, because I only use python3)
• pip is on version 9 and NOT 10

Here are both commands:

sudo pip uninstall pip
sudo python get-pip.py
