ImportError: <module 'setuptools.dist' from '/usr/lib/python2.7/dist-packages/setuptools/dist.pyc'> has no 'check_specifier' attribute
The command '/bin/sh -c python setup.py build  && python setup.py install' returned a non-zero code: 1

I added the following line to the DockerFile and it resolved it. It upgrades python setuptools to use latest version:

RUN pip install setuptools --upgrade

Open to suggestions of better ways to resolving this Note: Host machine: Ubuntu 14.04.5 LTS (trusty)
