我究竟做错了什么？
import {bootstrap,Component} from 'angular2/angular2'
@Component({
selector: 'conf-talks',template: `<div *ngFor="talk of talks">
{{talk.title}} by {{talk.speaker}}
<p>{{talk.description}}
</div>`
})
class ConfTalks {
talks = [ {title: 't1',speaker: 'Brian',description: 'talk 1'},{title: 't2',speaker: 'Julie',description: 'talk 2'}];
}
@Component({
selector: 'my-app',directives: [ConfTalks],template: '<conf-talks></conf-talks>'
})
class App {}
bootstrap(App,[])
错误是
EXCEPTION: Template parse errors:
Can't bind to 'ngFor' since it isn't a known native property
("<div [ERROR ->]*ngFor="talk of talks">
