Question

制作第一个Angular2程序会产生一些错误。虽然，我觉得我写得正确。有人可以帮我吗？

        packages: {'app': {defaultExtension: 'ts'}},
        map: { 'app': './angular2/src/app' }
      });

      System
          .import('hello_world_main')
          .then(null, console.error.bind(console));
    </script>
  </head>
<body>
   <my-app>Loading...</my-app>
</body>
</html>

hello_world_main.ts

import {bootstrap} from "angular2/platform/browser"
import {MyHelloWorldClass} from "hello_world_app.component"
bootstrap(MyHelloWorldClass);

hello_world_app.components.ts

import {Component, View} from "angular2/core";

@Component({
   selector: 'my-app'
})

@View({
  template: '<h2>Hello World !!</h2>'
})

export class MyHelloWorldClass {

}
