installation failed with setuptools postfix release

Hi!

I've got an errror when trying to install Sanic-Restplus (which uses your package).

       command: /usr/local/anaconda3/envs/project/bin/python -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/private/var/folders/kt/63f1vlpj55b89jhx87jvg6pm0000gn/T/pip-resolver-mvppy43f/wirerope/setup.py'"'"'; __file__='"'"'/private/var/folders/kt/63f1vlpj55b89jhx87jvg6pm0000gn/T/pip-resolver-mvppy43f/wirerope/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base /private/var/folders/kt/63f1vlpj55b89jhx87jvg6pm0000gn/T/pip-pip-egg-info-i1fq66rq

      Complete output (5 lines):

        File "/private/var/folders/kt/63f1vlpj55b89jhx87jvg6pm0000gn/T/pip-resolver-mvppy43f/wirerope/setup.py", line 3, in <module>

Looks like the assert in setup.py always except integer, but there are a few versions of setuptools with postfix (like setuptools-47.3.1.post20200622). After upgrade setuptools I resolve this issue, but I think it's better to avoid these problems. The version of my setuptools was correct, but can't be parsed anyway

Thank you!

Thanks! I will fix it soon.

I'm running into a similar issue when installing wirerope (or rather ring) using pip through Pants:

    Running command python setup.py egg_info
