bug? pyvan reports tomllib as an Import not found locally, and then tries to download from PyPI - but is built-in for Python 3.11

This seems to be a bug:

pyvan reports tomllib as an Import not found locally, and then tries to download from PyPI - but is built-in for Python 3.11

===START PYVAN BUILD===
Resolved python_version 3.11.6: (3, 11, 6)
Using Python-3.11.6 from:
 C:\Users\Sean.Ryan\Downloads\get-pip.py

Done!

But expect that pyvan sees tomllib as a built-in module for Python 3.11, so no need to try to find or download from PyPI ?

The used embedded python is a bit different. It doesn't have some packages (tkinter and some other I don't remember).

Package tomllib may be one of those missing packages from the embedded python.

Add this package to requirements: https://pypi.org/project/toml/ or manually copy/paste the tomlib package into resulted output of pyvan (I think is site-packages).

One of the advantage of using pyvan is that you can debug anything if something goes wrong (unlike pyinstaller where this is harder to do so). The result is just the embeded python + your scripts.

hi -
are not toml and tomllib two different modules?

I am using tomllib which is built in.

Far as i can tell, the pyvan output works ok (no missing modules or packages)

So the warning about tomllib missing seems to be a false positive

I specified in the docs also - unfortunalty pyvan doesn't work on linux and mac (only windows).

I don't have a Macbook to try to make it work there.. if you want you can contribute to this project.

pipreqs throws sometimes a false positive - the output of pyvan seems to work
