Issue while trying to run $pipenv --python 3.7

Question

I'm having issues while trying to run $pipenv --python 3.7 , in this case I am running it while inside my virtual environment. As I see, this could be having trouble with another virtual environment called venvAmazon , thar I don't need or use anymore.

I noticed that, when I created my actual virtual environment, 1. it didn't created a pipfile, 2. It was created in python 2.7. (I do have 3.7 in my pc), 3. It also throws me an error if I try to run outside the venv

During handling of the above exception, another exception occurred:

It seems this is a currently open issue with pipenv . It might worth trying what they suggest there:

pip install --upgrade --pre pipenv
