I've been charged with changing a PHP application to a RoR application. Everything's going well, but turbolinks is causing me some trouble. In order to fix this, I've decided to convert the existing .js libraries to .js.coffee

I have two .js libraries:

lightbox-2.6.js
modernizr.custom.js

These work perfectly. After converting these .js files to .js.coffee I incur the following error:

ExecJS::RuntimeError in Application#gallery

Installing node.js does not fix the problem.

Removing

//= require_tree .

from app/javascripts/application.js does solve the problem. However, according to this, removing this require method means that there is

an actual problem with ExecJS working properly with the JavaScript runtime on your system

Okay, I'll admit I don't really understand what to do with this. The .js works perfectly. When converted to .js.coffee this problem arises. I don't actually know what ExecJS is, either. Could someone clarify what's going on here? Why it doesn't work at all when converted to js.coffee and how I can fix this?
