Python3 Building a Pip Package 'setuptools is not defined'

Question

I have configured my files according to the PyPi documentation for building a pip package and it worked once to build when I was creating my test server package. I made a couple of changes and am now trying to build again, but it is failing with the following error

Found existing installation: setuptools 44.0.0

ERROR Backend subproccess exited when trying to invoke get_requires_for_build_sdist

I already have setup tools in both my pyproject.toml

[build-system]
requires = [
    "setuptools>=42",
    "wheel"
]
build-backend = "setuptools.build_meta"[build-system]
requires = [
    "setuptools>=42",
    "wheel"
]
build-backend = "setuptools.build_meta"

and included it in my setup.py file

from setuptools import setup, find_packages

with open("README.md", "r", encoding="utf-8") as fh:
    long_description = fh.read()

setup(
    name="ontology_processing",
    version="1.0.0",
    description="Climate Mind ontology processing code.",
    author="ClimateMind",
    author_email="omitted@omitted.com",
    url="https://github.com/ClimateMind/climatemind-ontology-processing",
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
    ],
    package_dir={"": "src"},
    packages=setuptools.find_packages(where="ontology_processing"),
    python_requires=">=3.6",
)

I've tried changing the versions of setuptools, but nothing has worked so far. I don't understand why this worked once, but is no longer working. Any suggestions are appreciated.

Answer 1

Okay I screwed up.

At the top I have

from setuptools import setup, find_packages

but I am not importing setuptools itself

Answer 2

I had the same error, but it was due to the inline comments I had written in the setup.cfg file.
