pip reporting erorr Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-QW1_6h/setuptools/

Question

I am unable to get python pip working by any means.

Please find below my commands and the output...

subscription-manager repos --enable rhel-server-rhscl-7-rpms
yum install python27-python-pip
scl enable python27 bash
which pip
pip -V
yum install python-devel

Output:

pip -V
pip 8.1.2 from /opt/rh/python27/root/usr/lib/python2.7/site-packages (python 2.7)

Honestly, I don't know what the issue is. As you would observe that any command results into the same error.
