I just down-ported my library to Python 2.7
Installing via pip install -e git+ssh://[email protected]/guettli/html_form_to_dict#egg=html_form_to_dict works on Python 2.7.
But it fails if I install it via pip:
pip install -v html-form-to-dict
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

What can I do, to make it installable for Python 2.7?
BTW I use this in setup.cfg (so this is not the problem):
[options]
python_requires = >=2.7
The better solution is to build a universal wheel, so that py2 users can also install from .whl and not fallback to .tar.gz release.
To do that, add into your setup call:
# in setup.py
from setuptools import setup
setup(
...
options={"bdist_wheel": {"universal": True}},
)
Now your wheel file will be named like html_form_to_dict-2022.3.1-py2.py3-none-any.whl, and it will be available to Python 2.7 users also. You can still upload the sdist (.tar.gz) alongside, if you want.
