setup(python_requires=">=3.9") seems not supported

[Dmitry Bufistov]

I get this error when have this argument in my setup.py:

pip install .

         _set_config(dist, "python_requires", SpecifierSet(val))
        File "/tmp/pip-build-env-koy0fqs3/overlay/lib/python3.10/site-packages/setuptools/_vendor/packaging/specifiers.py", line 708, in __init__
          split_specifiers = [s.strip() for s in specifiers.split(",") if s.strip()]
      AttributeError: 'NoneType' object has no attribute 'split'
      [end of output]

pyproject.toml:

[build-system]
requires = ["setuptools>=64", "setuptools_scm>=8", "packaging"]
build-backend = "setuptools.build_meta"

[project]
name = "evp"
dynamic = ["version", "entry-points", "dependencies", "authors", "classifiers", "scripts"]
description = "command line tool"

[tool.setuptools_scm]
version_file = "evp-cli/evp/__version__.py"

What is wrong?

The error is from setuptools

As far as I can tell setuptools-scm is unrelated

Id recommend using project.toml

Ah, makes sense! I forgot that I updated the setuptools to the latest version. Sorry for the noise!
The python-version worked in the pyproject.toml

Thank you!
