pip_fixer.sh

# Scenario:
# pip refers to python3
# python refers to python2
# pip install doesn't work for python instead works for python3
# Problem: Can't install modules for python2
#______________________________________________________________
# Solution:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
# Now pip install this way below (dnspython is the interesting module):
python -m pip install dnspython
