Importing module into setup.py can cause ModuleNotFoundError for uninstalled dependencies

[maximylius]

Hi, first of all thanks for building the tutorial!

When trying to build my first package with it, I ran into a problem which I wanted to report.
In setup.py the line from my_pip_package import __version__ can cause a problem, as it imports part of the package before the package dependencies are installed. For me this lead to a ModuleNotFoundError as I import my package modules into the _init.py_ file and those modules import my dependencies.

To solve this issue I would therefore suggest this solution from stack overflow:

• in setup.py: remove from my_pip_package import __version__ from and instead sepecify the version number directly setup(..., version="X.X",)
• in init.py: replace __version__ = 'X.X' with

from importlib import metadata
__version__ = metadata.version('my_pip_package')

No guarantee, that I am right here, but this finally solved my issue after several hours of looking elsewhere.
