the environmental background of the problems and what methods you have tried

Python 2.7.0
pbr5.1.1
setuptools 40.6.3

1. Directly use python setup.py build normal
2. You can also package normally by directly using python setup.py bdist_rpm . But executing the command under centos also reported an error.
