Python 3.10 job installs dependencies under Python 3.9 (Cookiecutter)

[cjolowicz]

See https://github.com/cjolowicz/cookiecutter-hypermodern-python/runs/6451683960?check_suite_focus=true

Possible reason: The CI for the Cookiecutter uses the pre-installed pipx to install Poetry. It looks like the pre-installed pipx uses Python 3.9, so Poetry is also installed under that version. As a result, Poetry uses Python 3.9 to create the project environment.

Good find. Embarassingly I had come across this a while back and forgot to investigate.

Do we need to use pipx here?

We can either:

1. Install pipx under the proper python, then proceed as usual
2. Just use pip itself to install nox and poetry

Happy to help with either.

Think your reasoning is right btw, on the 3.10 runs my pipx uses 3.8.

runner@fv-az426-664:~/work/nbpreview/nbpreview$ pipx runpip nox '--version'
pip 22.1 from /opt/pipx/shared/lib/python3.8/site-packages/pip (python 3.8)
runner@fv-az426-664:~/work/nbpreview/nbpreview$ python -V
Python 3.10.4

3. is use an action to handle installing poetry: snok/install-poetry.
