Problem with Angular 4



Hi, this is my first time trying C9, an I’m trying to create an app with Angular 4.
So, I’ve installed angular, I’ve created a new app, this is the message that I receive:

ng-app@0.0.0 start /home/ubuntu/workspace/ng-app
ng serve --host --port 8080

** NG Live Development Server is listening on, open your browser on http://localhost:8080 **

chunk {3} vendor.bundle.js, (vendor) 2.18 MB [initial] [rendered]
chunk {4} inline.bundle.js, (inline) 0 bytes [entry] [rendered]
webpack: Compiled successfully.

But, when I click on Preview Running Application, this is what I see

Could someone please give me a hint of what I’m doing wrong, thanks in advance.
