pipenv fails on Ubuntu 20.04
I was trying to use pipenv on Ubuntu 20.04 and got a perplexing error message. First, you must install pipenv. Install pipenv locally, not system wide, or you get into a whole different can of worms!
> pip3 install --user pipenvand be sure add ~/.local/bin to the head of your PATH environment variable. When you try to use pipenv, you get an error:
> pipenv --python 3.8 Creating a virtualenv for this project… Pipfile: /home/alan/expr/pydemo-10.05.a/Pipfile Using /usr/bin/python3.8 (3.8.2) to create virtualenv… ⠙ Creating virtual environment...ModuleNotFoundError: No module named 'virtualenv.seed.via_app_data' ✘ Failed creating virtual environment [pipenv.exceptions.VirtualenvCreationException]: Failed to create virtual environment.What is the problem here?

I was fortunate enough to stumble onto the answer in this thread concerning the underlying implementation of virtualenv:
