NPM install throws error

Nobody has claimed this yet.

Hi thanks for the awesome icons! I was trying to generate a new set of icons in a different color and I followed the instructions in the readme but I got the following errors when running npm install command. Can you please help? Thanks a lot.

Start with the README instructions for generating a new icon set and reproduce npm install on Windows using the reported Node.js version. Trace the mapnik node-pre-gyp and node-gyp failure, including the missing Python executable; done means dependencies install successfully and the documented icon-generation workflow can proceed.
