However, if a virtual environment in the shell is activated, it will try to run the debugpy library from the path ~/.virtualenvs/debugpy/site-packages/... with the python executable from the currently activated virtual env (which might be a completely incompatible version).

It assumes that you're using the same python version. The main idea behind this is that it avoids having to install debugpy in every virtualenv you create.

I would assume another viable route is to install debugpy into my virtual env. But it wont let me setup dap-python without providing the path in .setup().

If you install debugpy in every projects virtualenv you can use 'python3' or 'python' as path. It honors $PATH and virtualenv activation adds the virtual-env bin folder to the start of $PATH, so it will pick the right interpreter.
