Angular 2.0.0 Metadata_resolver怪异行为

Question

我正在将我的应用程序从angular2 RC5和angular WebPack脚手架迁移到angular 2 2.0.0和angular cli beta 14。

@Component({
  selector: 'tl-result-item',
  templateUrl: "./resultitem.component.html",
  styleUrls: ["./resultitem.component.scss"]
})
export class ResultItemComponent {

  @Input()
  result:Result;

  constructor(){}
}

你知道吗？

更新：

第一个错误可能与https://github.com/angularclass/angular2-webpack-starter#frequence-askeds-questions（第二个问题）有关，我有几个问题需要迁移到angular 2.0.0 final。

@NgModule({
  providers: [
    MetaService,
    Title,
    HttpInterceptor,
    {provide: ConnectionBackend, useClass: XHRBackend},
    {provide: Http, useExisting: HttpInterceptor},
    {provide: Configuration, useClass: ConfigurationDevelopment}
  ],
  imports: [
    BrowserModule,
    HttpModule,
    FormsModule,
    ReactiveFormsModule,
    // APP_ROUTER_PROVIDERS
  ],
  declarations: [
    AppComponent,
    ResultItemComponent,

    TimestampToMomentPipe,
    TimestampToTimePipe
  ],
  bootstrap: [AppComponent]
})
export class AppModule {
}

this.publicService.all().subcribe(response => {
      console.log(response);
});

this.publicService.all().subcribe(response => {
      deserialize(response)
});

未捕获错误：无法解析PublicInfoDAO：（？,？）的所有参数。

你想？？
