Packaging Tutorial Hatchling Build resulted in ModuleNotFound after installing libary; Setuptools works correctly

Using Ubuntu; python 3.10.6; working in the virtual environment.

Package                 Version
----------------------- -------
build                   0.10.0
example_project_andrewk 0.1.1
packaging               23.1
pip                     22.0.2
pyproject_hooks         1.0.0
setuptools              59.6.0
tomli                   2.0.1

Running the following commands in the python3 virtual environment would show the example_project_andrewk library available.

import pkg_resources
installed_packages = pkg_resources.working_set
installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
   for i in installed_packages])
print(installed_packages_list)

However the import statement from the python3 console from example_package_andrewk import example resulted in ModuleNotFound Issue.

Swapping to setuptools instead of hatchling seems to work correclty.

The name of the project needs to match the module name for hatchling to automatically find it. If you want them different, you can tell hatchling where your package(s) are via an extra config setting.

Ah, that makes sense Thank you for the reply.
