SystemJS / Aurelia app breaks down to PhantomJS

I'm trying to get some tests done in Phantom, but Aurelia / SystemJS seems to crash on Phantom.

I tested it with my own app and Aurelia contacts example, they are slightly different. I'll list the results here, which I've captured:

contact app:

CONSOLE: INFO [aurelia] Aurelia Starting (from line #undefined in "undefined")

my application:

FWIW both work fine in Chrome / FF and I am running PhantomJS 1.9.8 on OS X 10.10

Also here's the Phantom script I'm using to test these and output from the console:

var webPage = require('webpage');
var page = webPage.create();

page.open('http://localhost:9001/', function() {
  page.onConsoleMessage = function(msg, lineNum, sourceId) {
    console.log('CONSOLE: ' + msg + ' (from line #' + lineNum + ' in "' + sourceId + '")');
  };
});

      

        
        
        
      

    

to launch the contacts application (first example) do the following:

git clone git@github.com:aurelia/app-contacts.git
cd app-contacts
npm install && jspm install
gulp watch

      

        
        
        
      

    

It is assumed that you have installed node

, jspm

and gulp

. Then you can run the above phantomjs script.

Any ideas?
