although I installed python and can run it from console:

# python
Python 2.7.3 (default, May  9 2014, 12:18:32) 
[GCC 4.8.2] on linux2

and set up PATH in ~/.bashrc:

export PYTHONPATH=$PYTHONPATH:/Python-2.7.3
export PATH=$PATH:/Python-2.7.3

and done . ~/.bashrc

For anyone encountering this issue on Ubuntu 16.04...
node-gyp can't use Python 3.5.X which seems to the be the default that ships with 16.04. I read somewhere that 16.04 was supposed to ship with Python2 as well but I can't find it on my install.

I fixed the above issue by:

apt-get update     
apt-get install python2.7    
ln -s /usr/bin/python2.7 /usr/bin/python 

Now when node-gyp goes looking for python it will hit your Python2.7 install and load correctly.
