Sounds like someone has never been asked to clone and run software targeting Python 3.x when their system-installed Python is 3.y and the two are incompatible.

Then you use pyenv and pyenv virtualenv.

    pyenv install 3.9.47
    pyenv virtualenv 3.9.47 my app
    git clone …/myapp
    cd …/myapp
    pyenv local myapp
    pip install -r requirements.txt

Is it annoying, maybe, but I normally don’t trust system deps for anything.

Sounds like someone is making assumptions on the way I work :) As a matter of fact I have and the solution is pyenv. Node has a similar utility called n.
