Error Initiating the Generator: `You don't appear to have Python installed.` - Python 3.7

Error

I attempted to follow the quickstart example running inside a pipenv shell. I DO have Python 3.7 installed.

? Which flavor of database will you be using with your API?
Make sure you've got it installed first, of course! (Use arrow keys)
> PostgreSQL
  MySQL
  SQLite
  None / Other
You don't appear to have Python installed. You should fix that post-haste! Try running me again when you have that sorted out.

Did you fix it? I am having the same problem.

I was attempting to run this in a container. The container does not have "which" installed. I got around this error by a) making sure I had /usr/bin links to python & pip b) making sure I had which installed (the app uses which to find python)
