不能綁定到「數據」，因爲它不是「教數據」的已知財產

Question

爲什麼我會收到以下錯誤： Can't bind to 'data' since it isn't a known property of 'teach-data'.

試圖當：

<teach-data *ngIf="selectedData" [data]="selectedData"></teach-data> 

TeachDataComponent

..some imports 
export class TeachDataComponent implements OnInit { 

    public requests; 
    @Input() data; 

    constructor(private http: Http, private JwtService:JwtService, 
    private _service: NotificationsService) { 
    } 

    ngOnInit() { 

    } 

*曾在RC.4

* Hapenned嘗試後升級到Angular 2 RC.5。

Answer 1

確保你已經關注了所有的steps for migrating to RC 5。特別是step 2: Create an NgModule。嘗試導入teach-data組件並將其添加到@NgModule語句的「聲明」部分。
