Cannot compile app to work

[Setitch]

I have small problem when using library - i mean, gulp works perfectly, but then due to some tools error (cannot find and null pointers when accessing them) the sketchpad is never initialized - and this only happenes with the version from git.
Tried to used the sketchpad.js file from the website and it worked - but its much different than the version built by gulp form this git archive. Is there anyway to make the git version actual or get some information about commercial version of spetchpad?
