Problem with Angular 4

angular

#1

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 0.0.0.0 --port 8080

chunk {4} inline.bundle.js, inline.bundle.js.map (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.
