角度 2 |类型“{}”的指令参数不可分配给

我是 Angular 2 的菜鸟。我正在做 YouTube 教程，但每个教程都有directives:我被困的部分。

应用程序组件.ts

import { Component } from '@angular/core';
import { HeaderComponent } from './components/header/header.component'
@Component({
  selector: 'my-app',
  template: '<h1>Hello</h1><header></header>',
  directives: [HeaderComponent]
})
export class AppComponent { }

错误输出为：

Argument of type '{ selector: string; template: string; directives: typeof HeaderComponent[]; }' is not assignable to parameter of type 'ComponentMetadataType'.at line 6 col 3

header.component.ts

import { Component } from '@angular/core';

@Component ({

  selector: 'header',
  template: '<h2>hit!</h2>'

})
export class HeaderComponent { }

Here's an screenshot of the error

directives财产被移除于RC.6

你应该把它移到declarations你的财产NgModule装饰者

@NgModule({
  imports:      [ BrowserModule ],
  declarations: [ AppComponent, HeaderComponent ], <== here
  bootstrap:    [ AppComponent ]
})
export class AppModule { }
