无法使用打字稿向我的 angular 2 应用程序添加新组件 [英] Can't add a new component to my angular 2 app with typescript

问题描述

我使用的是 Angular 2 CLI，并使用 ng 生成组件 MyComponent 创建了组件MyComponent".据我所知，我必须将组件添加到 @Component 装饰器的指令键值对中，但此时打字稿编译失败，说:

I'm using Angular 2 CLI and I created the component "MyComponent" with the ng generate component MyComponent. As far as I know I have to add the component to the directive key-value-pair of the @Component decorator, but the typescript compilation fails at this point, saying that:

ERROR in [default] /Users/Philip/Desktop/Angular2/src/app/app.component.ts:8:2 
Argument of type '{ selector: string; template: any; styles: any[]; directives: typeof MyComponentComponent[]; }' is not assignable to parameter of type 'Component'.
  Object literal may only specify known properties, and 'directives' does not exist in type 'Component'.

这是我的应用代码:

import { Component } from '@angular/core';
import { MyComponentComponent } from './my-component/my-component.component'

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  directives: [MyComponentComponent],
})
export class AppComponent {
  title = 'app works!';
}

我没有动生成组件的代码，以防万一:

I didn't touch the code of the generated component, but just in case:

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

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})

export class MyComponentComponent implements OnInit {

  constructor() {

  }

  ngOnInit() {
  }

}

推荐答案

错误本身表明指令不存在于 组件，因为它已被弃用.试试下面显示的代码，

Error itself says that directives doesn't exist in Component as it has been deprecated. try this code shown below,

import { MyComponentComponent } from './my-component/my-component.component'
import {CUSTOM_ELEMENTS_SCHEMA} from '@angular/core';

@NgModule({
   ...
   ...
   declarations:[AppComponent,MyComponentComponent], //<---need to declare 
   schemas:     [CUSTOM_ELEMENTS_SCHEMA]             //<---added this line
})

并从 AppComponent 中删除 directives:[MyComponentComponent].
