VSCode Python: Error while enumerating installed packages [duplicate]

Question

My long-successful VSCode Python setup broke inexplicably.

Please, what does the error below mean? First the recommended Python 3.12 can't find _tkinter. I try an older installed version and get this. I can't use pip either, it says "externally managed environment". I'm lost.

Answer 1

fixed after installing importlib-metadata and debugpy in my venv

Answer 2

This solved the issue for me (from https://github.com/microsoft/debugpy/issues/1379):

Locate debugpy/common/log.py under site-packages (following the path you see in the output). Find the line in that file that says:

swallow_exception("Error while enumerating installed packages.")}

replace it with: swallow_exception("Error while enumerating installed packages.", level="info")

Is incredible this hasn't been released yet.
