Can install new PyPi module with pip, but can't import it myself?

February 22, 2023

So I’m trying to add a new script I wrote, fakesky, to PyPi as a module. I uploaded it to PyPi, and pip will let me install it successfully, but every time I try to import it, I get the following error:

ModuleNotFoundError: No module named 'fakesky'

The structure of the upload is as follows:

fakesky ->
  setup.py
  setup.cfg
  README.txt
  LICENSE
  src ->
    __init__.py (empty file)
    fakesky.py
    results_BB.txt (necessary file that fakesky.py reads)

And the relevant files are as follows:

setup.py:

from setuptools import setup, find_packages
setup(
    name='fakesky',
    version='1.0.2',
    license='CC0 1.0',
    author="Drew Weisserman",
    author_email='drewweis@umich.edu',
    packages=find_packages('src'),
    package_dir={'': 'src'},
    url='https://github.com/drewweis/fakesky',
    keywords='sky image',
    install_requires=[
        'matplotlib',
        'numpy',
        'pandas',
        'scipy',
        'astropy'
      ],

)

setup.cfg:

[metadata]
description-file=README.md
license_files=LICENSE.rst

I performed the following commends to upload it:

[cd to inside fakesky folder]
python3 setup.py sdist
twine upload dist/*

Can anyone tell me what I’m doing wrong?

>Solution :

The directory structure is wrong. Recreate like this:

fakesky ->
  setup.py
  setup.cfg
  README.txt
  LICENSE
  src ->
    fakesky ->
      __init__.py (empty file)
      fakesky.py
      results_BB.txt (necessary file that fakesky.py reads)

By the way, I recommend to name the module differently than the top-level package name, to avoid confusing imports like from fakesky import fakesky.
