I created a package and uploaded it to test.pypi.org: https://test.pypi.org/project/name-generator-nicomp/0.0.2/

The logic reads a text file that I want to include in the package. In my initial design I put the text file in its’ own folder and my logic ran just fine on my local machine.

I installed the package from test.pypi.org onto a different computer using pip:

python3 -m pip install --index-url https://test.pypi.org/simple/ name-generator-nicomp --upgrade

Then, I run this script:

if __name__ == "__main__":
    from name_generator_nicomp.NameGenerator import NameGenerator
    nameGenerator = NameGenerator()

and it fails inside the package code on this line:

    with importlib.resources.open_text("src.data", self.noun_file) as my_file:

The error is:

ModuleNotFoundError: No module named 'src'

Looking in the .gz file created by the build script, the src folder is there and the data folder is inside it. The repo on test.pypi.org also has the folder structure in it. It can be downloaded and verified here: https://test.pypi.org/project/name-generator-nicomp/0.0.2/#files

However, when I look at the installation of the package on my local machine, all the files (code and data) are in one folder and there are no other folders at all.

My .toml file is

version = "0.0.2"

  { name="xxx xxxxxx", email="xxx.com" },
