angular - 为什么我在刚启动的 Angular2 应用程序中会收到此错误？

Question

我刚开始编写一个全新的 angular2 应用程序，我从中克隆了它 https://github.com/angular/quickstart

为什么会出现此错误？

app/app.component.ts(8,3): error TS2345: Argument of type '{ moduleId: string; selector: string; templateUrl: string; directives: string[]; }' is not assignable to parameter of type 'Component'. Object literal may only specify known properties, and 'directives' does not exist in type 'Component'.

app.component.ts

import { Component } from '@angular/core';
import { NavbarComponent } from './components/navbar/navbar.component';

@Component({
  moduleId: module.id,
  selector: 'my-app',
  templateUrl: 'app.component.html',
  directives: [NavbarComponent]
})
export class AppComponent  {  }

navbar-component.ts

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

@Component({
  moduleId: module.id,
  selector: 'navbar',
  templateUrl: `navbar.component.html`,
})
export class NavbarComponent  {  }

Answer 1

从 app.component.ts

中删除以下行

directives: [NavbarComponent]

并将其添加到app.module.ts

@NgModule({
  imports:      [ BrowserModule ],
  declarations: [ AppComponent, NavbarComponent ], << add here
  bootstrap:    [ AppComponent ]
})

从 2.0.0-rc.6 开始不再提供指令
