Since the required python version now is 3.8 I use the docker image node:18-bullseye-slim which allows me to install python 3.9`.

However now I get following error:

Hi @skwde

I guess a pyproject.toml exists, but you use setup.py to build. Same issue: pycasbin/django-orm-adapter#26

Here are some solutions:

1. Migrate from setup.py to pyproject.toml
2. use [email protected]
3. Wait until I add an option to force the use of setup.py, even if pyproject.toml exists

[skwde]

Thanks for pointing it out.

I already migrated most to setup.cfg a while back.
Thus, my setup.py is fairly basic, I only have

import setuptools

setuptools.setup()

in it. So in principle I can just remove it?!

When I do so I still get the same error above. Any ideas?

[abichinger]

If pyproject.tomlexists in your project, semantic-release-pypi is going to set the version inside pyproject.toml. This causes the error above, because there is no project section in your pyproject.toml

I recommend migrating all metadata to pyproject.toml and deleting setup.py and setup.cfg

[skwde]

Alright, that worked. Thanks.

For others coming here, transition to pyproject.toml is fairly straight forward using

• https://github.com/gvalkov/setuptools-py2cfg for setup.py to setup.cfg

and then

• https://github.com/abravalheri/ini2toml/ for setup.cfg to pyproject.toml

Note, I also had to make sure ensurepip is available.
