pkg_resources.DistributionNotFound: The 'pipenv==2018.10.13' distribution was not found and is required by the application

Question

I've reinstalled pip and pipenv due to some broken package with ansible. Now, it seems like my pip dependencies are all screwed. Any suggestion or help is greatly appreciated.

$ which python2
 /usr/local/bin/python2

$ which python3
/usr/local/bin/python3

$ which pipenv
/usr/local/bin/pipenv

Solution 1

I had the same problem. You should reinstall pipenv using the same package manager you used the first time.

• If the installation was done using pip, then:

  pip uninstall pipenv
  pip install pipenv
  

• If you are using brew, then you must run the commands exposed by Andrei

  brew uninstall pipenv
  brew install pipenv
  

To check if pipenv installation was successfully completed, run: pipenv --version

From the comments, alternatively use:

brew reinstall pipenv

Solution 2

This should fix the problem too:

pipenv --rm
pipenv check
pipenv sync

I run into this problem from time to time when updating python using anaconda.

Or just brew reinstall pipenv

What's actually happening in this situation? I have the brew version and I've had this happen to me twice now.

@wojonatior I would be interested to know this as well

@Connor@wojonatior, I believe this had to do with pip and brew libraries are conflicted as to which one to use, that's why I always have each project for each virtualenv
