ModuleNotFoundError When running own Project installed from PyPi using Setuptools and Wheels

When I install one of my own Python applications from PyPi, it fails to run citing

File "/home/me/.local/lib/python3.9/site-packages/refrapt/refrapy.py", line 20, in from classes import ( ModuleNotFoundError: No module named 'classes'.

I have the following directory layout in my local area:

/refrapt
  setup.py
  /refrapt
    classes.py
    helpers.py
    refrapt.conf
    refrapt.py
    settings.py
    __init__.py

To build the project, I'm using setuptools, running the following command: python setup.py sdist bdist_wheel This builds and works happily enough, and I'm able to upload the resulting /dist.

I then install the project using pip3 install refrapt. When I run it using refrapt, I get the error ModuleNotFoundError above.

When I run the development code locally, it runs fine, but installed via pip, it is failing. I assume it's a problem with my setup.py, but this is my first time and I haven't really a clue what is correct. I tried adding the init.py (which is empty) as suggested by some python docs, but to no avail. The contents of setup.py are as follows:

import pathlib
from setuptools import setup, find_packages

HERE = pathlib.Path(__file__).parent

README = (HERE / "README.md").read_text()

setup(
    name='Refrapt',
    version='0.1.5',
    description='A tool to mirror Debian repositories for use as a local mirror.',
    python_requires='>=3.9',
    long_description=README,
    long_description_content_type="text/markdown",
    packages=find_packages(),
    install_requires=[
        'Click >= 7.1.2',
        'Colorama >= 0.4.4',
        'tqdm >= 4.60.0',
        'wget >= 3.2',
        'filelock >= 3.0.12'
    ],
    classifiers=[
        "Development Status :: 4 - Beta",
        "Operating System :: Microsoft :: Windows :: Windows 10",
        "Operating System :: POSIX :: Linux",
        "Programming Language :: Python :: Implementation",
        "Topic :: System :: Archiving :: Mirroring"
    ],
    keywords=['Mirror', 'Debian', 'Repository'],
    entry_points='''
        [console_scripts]
        refrapt=refrapt:refrapt
    ''',
)

If anyone could help, I'd greatly appreciate. I'm out of my depth on this one, and haven't been able to find an answer so far.

Potentially I've found out the answer to my question, but it's not the answer I wanted.

I spun up a virtual environment, and installed an application that I've used before via pip. When I went to run the app, I got the ModuleNotFoundError: No module named 'app'.

I tried to run it manually via the .py file by using python .\.venv\Lib\site-packages\app\cli.py, which resulting in the same error.

Seems to be something about the environment setup in Windows VS Code that just doesn't operate the same as on a Linux machine.

I guess I'll just have to remove the "refrapt." prefix from import statements when developing locally, and then add it back when pushing to GitHub.

from classes import …

In Python 2 this was relative import — the statements imports classes from the current directory of the importing module.

But in Python 3 it was changed to absolute import. The import fails because there is no a global module or a package named classes. You need to convert the import to absolute or relative. Either

from refrapt.classes import …

or

from .classes import …
