Invalid dash-separated key 'license-file' in 'metadata' (setup.cfg) Error

[polatbilek]

Setuptools create an error of setuptools.errors.InvalidConfigError: Invalid dash-separated key 'license-file' in 'metadata' (setup.cfg), please use the underscore name 'license_file' instead. with current setup.cfg file. You need to switch some kebab cases into snake. To make our project be able to install requirements I forked the project and fixed it (Couldn't find an instruction to how to create a branch and PR for fixes in this project's README, so I forked and fixed) https://github.com/polatbilek/email-normalize

Anyone can create a wheel with command of python setup.py bdist_wheel --universal to create his own wheel package and you can install that package via pip to make email_normalize work again until this problem is fixed.

Did setuptools roll out an update that broke this?
