Angular2 RC1在PropDecoratorFactory上未找到帶有@Input的指令注釋

Question

我正在嘗試將輸入參數傳遞給組件，但遇到此異常：browser_adapter.ts：78例外：錯誤：未捕獲（承諾）：在PropDecoratorFactory上找不到指令注釋

我嘗試了此處描述的解決方案，但對我來說並沒有解決問題：

這是我的代碼：

import {Component, provide, Input} from '@angular/core';
import {bootstrap} from '@angular/platform-browser-dynamic';
import {Http, HTTP_PROVIDERS} from '@angular/http';
import {RouteConfig, ROUTER_DIRECTIVES, Router, ROUTER_PROVIDERS} from '@angular/router-deprecated'

@Component({
  selector: 'sub',
  template : `<p>input: {{someInput}}</p>`,
  directives: [Input]
})
export class SubComponent {
  @Input() someInput: Number;
}

@Component({
  selector: 'home',
  template : `<p>home</p><sub [someInput]="someInput"></sub>`,
  directives: [SubComponent]
})
export class HomeComponent {
  someInput: Number = 123;
}

@Component({
    selector: 'my-app',
    template: '<h1>here!</h1><router-outlet></router-outlet>',
    directives: [ROUTER_DIRECTIVES],
    providers: [ROUTER_PROVIDERS]
})
@RouteConfig([
    { path: '/home', name: "Home", component: HomeComponent, useAsDefault: true}
])
export class App {
}

Answer 1

從directives數組行中刪除Input

@Component({
  selector: 'sub',
  template : `<p>input: {{someInput}}</p>`,
  directives: [Input] // <---- this is causing it
})
export class SubComponent {
  @Input() someInput: Number;
}

Input不是指令，它是組件輸入的修飾符，僅在類內部使用，而不在html上使用。
