Uncaught ReferenceError: System is not defined

I am trying to port an old angular app with angular-ui-router to angular 2 using https://github.com/ui-router/ng1-to-ng2 and on runtime I get the following error

Uncaught ReferenceError: System is not defined

I am guessing it is looking for SystemJS, but I don’t think Meteor is using SystemJS for their module system.

Trajano,

Ever solve this? I am getting this a lot when attempting to import Ng2 or angular2 npm packages and use them.
