Do you run eventgen with SA-eventgen?
No

If you are using eventgen with pip module mode (please complete the following information):

• python version: 3.7 miniconda
• Virtual Env is used: Yes

I'm also seeing this issue on various python versions, as well as when I try to build/install it manually:
$ python3 setup.py sdist
$ pip3 install dist/splunk_eventgen-7.1.0.tar.gz
@li-wu this looks like it has trouble parsing pyproject.toml, can you take a look?

@jmeixensperger sure, let me take a look.
