Getting this?

[root@rmq01 ~]# pip3 install –user git+https://github.com/powerline/powerline.git@master
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install –user` instead.
Collecting git+https://github.com/powerline/powerline.git@master
  Cloning https://github.com/powerline/powerline.git (to master) to /tmp/pip-i_onc12r-build
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-i_onc12r-build/setup.py", line 11, in <module>
        from setuptools import setup, find_packages
    ImportError: cannot import name 'setup'

Solve it by running this:

[root@rmq01 ~]# yum reinstall python3-setuptools.noarch

Seems package files were corrupted.  

Cheers,
