No need for a novel mechanism - there are plenty of available solutions to add validation to python

Pkl doesn't come preinstalled on machines - so you'll have to install it as well

This is the real friction point, but is it a bigger friction point than having to adopt yet another DSL?

Yesterday, I created a virtualenv, then ran `pip install`, only to see it fail. I found out that even `pip --version` was failing. I discovered that running `python -m ensurepip --upgrade` would fix pip. It did fix pip, but `pip install` still didn't work properly. I figured out that pip was reporting a different version of python than the one virtualenv is using. Running `python -m pip install --upgrade pip` upgraded pip, which should have been accomplished with the previous ensurepip command. Finally, everything was working properly.

I experienced these problems after years of experience in python. To answer the question. Yes, it's worth adopting yet another DSL than using python.

Did you activate the virtual environment?

For all the flak python gets, dependency setup is pretty simple if you're not flailing around aimlessly

  python3.12 -m venv --copies --clear --upgrade-deps ".venv"
  source ".venv/bin/activate"
  python -m pip install --upgrade pip setuptools wheel
  python -m pip install --editable .

Yes, I had activated the virtual environment. Thanks for the guide. It works without problems. I had used `virtualenv venv -p /usr/local/bin/python3.12` in my setup. Yours seems to be a better way.

That right there is the main problem with python dependency management - too many damn ways to do the same thing.

And to think "There should be one-- and preferably only one --obvious way to do it." is in the Zen of Python...
