Switching Python version (3.9 → 3.8) installed by Homebrew

Question

It’s a very similar situation like described here, but vice versa. I have Python 3.8 installed via Homebrew and updated that to 3.9:

% brew list --formula | grep          


        

Answer 1

Well, sometimes it helps to ask the question to find the solution on your own – one of the great things of StackOverflow, by the way.

The hint is in the warning of pipenv: "Your Pipfile requires python_version 3.9".

I simply did

rm Pipfile
rm Pipfile.lock

and then it worked:

pipenv install google-ads

Well, at least pipenv worked correctly with Python 3.8. There is still an issue with google-ads, but that's another story.

Probably it would have been enough to change the Pipfile:

[requires]
python_version = "3.8"
