this lines cause the error (TypeError: Cannot read property 'prototype' of undefined) :

isForType(type) {
return Object.prototype.isPrototypeOf.call(this.type.prototype, type.prototype);
}

type is undefined

I got it working, you have to use the fork from SeanSobey (https://github.com/SeanSobey/ChartjsNodeCanvas).
You have to require it in your file and also a date adapter.
