python - pipenv fails installing Django

Question

I'm trying to create virtual environment in PowerShell with Python 3.9, using the pipenv command, but when I run pipenv install Django it says this:

Creating a virtualenv for this project...
Pipfile: C:UsersAlnourrusDesktopcfeprojPipfile
Using C:/Program Files/Python39/python.exe (3.9.1) to create virtualenv...
[   =] Creating virtual environment...New python executable in C:UsersAlnourrus.virtualenvscfeproj-gGpEVtIiScriptspython.exe

ERROR: virtualenv is not compatible with this system or executable
Note: some Windows users have reported this error when they installed Python for "Only this user" or have multiple versions of Python installed. Copying the appropriate PythonXX.dll to the virtualenv Scripts/ directory may fix this problem.

Failed to create virtual environment.

Answer 1

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 )

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