So i installed from the script and when it finished there were 3 WARN messages saying

npm WARN prefer global coffee-script@1.10.0 should be installed with -g
npm WARN prefer global colorguard@1.2.0 should be installed with -g
npm WARN prefer global jsonlint@1.6.2 should be installed with -g

so i reimnstalled those using -g and that went ok. renamed the config file and did npm start. no dice. i got

magicmirror@2.0.0 start /home/pi/MagicMirror
electron js/electron.js

fs.js:557
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
^
