can't run Ext JS Kitchen Sink example

Question

Je suis nouveau sur extjJS6 and i try to run examples, i have a problem to run this treeMap https://examples.sencha.com/extjs/6.5.0/examples/kitchensink/#d3-view-treemap, i put all code (Model, View, controller) in one js file, is that can cause an error? When i run i don't find exceptions but there are two message in my console:

• GET http://localhost/Ext/app/ViewController.js?_dc=20170104130840 net::ERR_ABORTED

• GET http://localhost/Ext/d3/hierarchy/TreeMap.js?_dc=20170104130840 net::ERR_ABORTED

Someone had test this example?
