我正在尝试Angular 2的快速入门，但是我不知道它为什么不起作用。我已经找到了一些类似的问题，但是我没有找到答案。有人能帮助我吗？
这是我的代码。
app.component.ts
import {Component} from 'angular2/core';
@Component({
selector: 'my-app',
template: '<h1>My First Angular 2 App</h1>'
})
export class AppComponent { }
main.ts
import {bootstrap} from 'angular2/platform/browser'
import {AppComponent} from './app.component'
bootstrap(AppComponent);
