How do I use this library in React?

I installed the lib via NPM, but I got this error:Uncaught Error: Cannot find module 'createjs'

I tired "import createjs from 'createjs'" and "import 'createjs'", neither is working, I modified webpack config, and I got this error:cannot read property 'prototype' of undefined.

What should I do? I used create-react-app to create the app. I have no idea what causes the problem.
