ImportError: No module named "pip._vendor.distlib.scripts" when I try to install framework using python pip

When I run this command on CentOS4.9 such error occurs. I try to search it on google but couldn't find it. Looks like I am the first person to encounter such a problem.

# install install fabric

I went to / usr / local / lib / python 2.7 / site-packages / pip-7.0.1-py2.7.egg / pip / _vendor / distlib. Scripts.py file.
