Pytest doesn't *seem* to be using Python version installed with asdf

Cross posted from https://stackoverflow.com/questions/77463416/with-asdf-installed-python-why-does-pytest-use-a-differentpython-version-than-t

I have installed several Python versions using asdf. I am also using Pipenv to manage dependencies. Although I have Python 3.9.4 referenced in my Pipenv file, and asdf reports that I'm using Python 3.9.4, pytest reports that it's using 3.11.6.

For example:

tmoney@tmoney-linux:~/code/wp1$ asdf list python
  3.12.0
  3.7.16
 *3.9.4
tmoney@tmoney-linux:~/code/wp1$ cat .tool-versions 
python 3.9.4
tmoney@tmoney-linux:~/code/wp1$ cat Pipfile

Turns out I have to explicitly set the Python version on pipenv when using asdf:

pipenv --rm
pipenv --python 3.9.4

For me, also using asdf, part of the issue was that the python pinned in .tool-versions was different from project.toml. I had some dependencies installed from another project so those were working, but pytest for whatever reason wasn't.

Also for whatever reason, Poetry was still stuck on the other Python version until I updated to Poetry to 2.2.1 (perhaps I should have tried more cache clearing).
