Thank you for your help.

The installation is failing because it's looking for python3 headers. Looking at https://pypi.python.org/pypi/getch there are two source distributions listed, getch-1.0-python2.tar.gz and getch-1.0.tar.gz.

For python 2 you need the former of those, but it looks like the latter one is being chosen (same thing happens for me). I'm not sure if/how pip is supposed to be able to know how to choose the correct one, but you can choose manually:

copying the link, 

pip install https://pypi.python.org/packages/source/g/getch/getch-1.0-python2.tar.gz#md5=586ea0f1f16aa094ff6a30736ba03c50

works for me
