Windows 10, Python 3.8.3, pipenv 2020.6.2
I managed to solve this by typing in the full path to the python.exe:
pipenv install --python=“C:\Users\my_name\AppData\Local\Programs\Python\Python38\python.exe”
Viola! Virtual environment created.
this issue still persists on win10 with python 3.8.3 and pipenv 2020.6.2
I have solved this by reverting to
pip install pipenv==2018.11.26
