I am trying out Angular2 and I started with an example here
I can run npm install and npm start without errors, but the Component is not loaded. The selector points to my-app but the content in the tag is never replaced. I end up seeing 'Loading...' in the browser.
All code is directly copied from the sample using copy paste. I have not edited anything at all. I wonder if the sample simply does not work or if this could be something caused by my development environment?
