Installing on Python 3.6 throws error

[sj-curtin]

Hello 👋

Trying to install it on Python 3.6.12 and is saying it needs setuptools>=61.0 however setuptools has dropped support in v59.7.0: https://github.com/pypa/setuptools/blob/main/CHANGES.rst#v5970

Trying to figure out why setuptools v61 specifically but cannot pin point where it uses it 🤷

By default pip is installing v1.2.5 on my mac...

See my logs:

 -> $ python --version

Ah, I should have checked that - mindlessly set it to the version I was using without knowing it didn't support older python versions. I'll repackage with an easier requirement and post a new version later today.

As a temporary workaround you can try checking out the source directly and modifying the "requires" line in pyproject.toml, then you should be able to build a usable source package with python -m build -s (if you have the build package installed)
