Error in pyp2rpm setup command: 'tests_require' must be a string or list of strings containing valid project/version requirement specifiers

[patsevanton]

Try install pyp2rpm on CentOS7.

If install pyp2rpm from rpm package, then pyp2rpm don`t have template epel7. Therefore, I install through pip.

If you just start the installation via pip
pip install pyp2rpm

I will get an error

setuptools_scm.version.SetuptoolsOutdatedWarning: your setuptools is too old (<12)

Updating setuptools to version 12
pip install setuptools==12
I get an error

1. use Python 3 (python3 -m pip)
2. after you update setuptools and setuptools_scm, also install pip install wheel

Does that help?
