ImportError: No module named packaging.version

Recently, I face ImportError: No module named packaging.version  and I would like to share knowledge to fix that problem.

Terminal:

pip --version
pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)


I am trying to upgrade pip

python -m pip install -U pip
