If you installed Python using a package manager, it should already be on your path- but if not: add it like this:
export PATH="$PATH:/usr/local/bin/python (or wherever you installed python to)
Node-gyp requires 2.x and cannot use Python3 (do you have the right version installed?).
See Running Python on Windows for Node.js dependencies for Windows to make sure you have your environment variable set.
