pipenv shell fails to create virtual environment

I am trying to run a Django project using pipenv shell. But when I enter the command pipenv shell, it fails.

Failed to create virtual environment.

Everything was okay when I was using pipenv shell in macOS Mojave, now I'm using Catalina version 10.15.1 and it's not working at all. I've tried upgrading pip, removing and reinstalling pipenv but same thing happens. :'(

Can anyone help me solve this problem?

P.S. I want to use virtual environment with pipenv shell, not with python -m venv

Solution

  • It appears pipenv is crashing because it attempts to create a folder that already exists. Try clearing the virtual env with 

    rm -rf `pipenv --venv`

    If that fails because pipenv complains there isn't an associated virtualenv, you'll have to skip the shortcuts and look at the error message for what folder it doesn't like and delete it ( make sure you're deleting a subfolder of /virtualenvs and not something important like the pipenv bin )

    For example here you'd do the following: 

    rm -rf /Users/juyeong/.local/share/virtualenvs/django_workspace-CfQ2tbWB/
