Can I request a hack? How do I handle several different versions of Python installed, which one is used for pip stuff, and how sudo/running as services changes all of this.
You can use pyenv. it will handle everything. https://github.com/pyenv/pyenv
There are like 10,000 different solutions, but I would just recommend using what's built in to python
If you have multiple versions installed you should be able to call
python3.12to use 3.12, etcBest practice is to use a different virtual environment for every project, which is basically a copy of an existing installed python version with its own packages folder. Calling pip with the system python installs it for the entire OS. Calling it with sudo puts the packages in a separate package directory reserved for the operating system and can create conflicts and break stuff (as far as I remember, this could have changed in recent versions)
Make a virtual environment with
python3.13 -m venv venvthe 2nd one is the directory name. Instead of calling the system python, call the executable atvenv/bin/python3If you do
source venv/bin/activateit will temporarily replace all your bash commands to point to the executables in your venv instead of the system python install (for pip, etc).deactivateto revert. IDEs should detect the virtual environment in your project folder and automatically activate ithttps://github.com/jdx/mise
I started using hatch lately and really like how I can manage everything from the pyproject.toml file
