Angular2 版本 RC.6 “指令"内部@Component 错误 [英] Angular2 version RC.6 "directives" inside @Component Error

问题描述

我使用的是 Angular2，并且已经从官方网站下载了 package.json.当我尝试在 @Component 装饰器中使用指令"时，出现此错误.

I am using Angular2 and have downloaded package.json from the official website. When I am trying to use "directives" inside @Component decorator I am getting this error.

我附上了我的代码错误:

I have attached my code ERROR:

[ts]
Argument of type '{ selector: string; template: string; directives: string; 
}' is not assignable to parameter of type 'ComponentMetadataType'.

Object literal may only specific known properties, and 'directives' does not
exist in type 'ComponentMetadataType'.
(property) directives: string

这是我的代码:

import { Component } from '@angular/core';
import { PeopleListComponent } from './people-list/people-list.component';

@Component({
 selector: 'my-app',
 template: '<h1>{{ title }}</h1>',
 directives: ''   //ERROR //NOT ABLE TO RECOGNIZE
})

export class AppComponent { 
  title = "My title";
} 

这是我的 package.json:

推荐答案

简单...

问题在于指令:''

problem is with directives: ''

作为一个数组，它应该是 directives: [ ]

as its an array it should be directives: [ ]

更新:在RC6 OR之后的版本中，你有@NgModule.在RC6 OR之后的版本中，你必须声明pipes和指令 您将在 @NgModule 中使用，如图所示...

Update: In RC6 OR later version, you have @NgModule. In RC6 OR later version, you have to declare pipes and directives that you are gonna use within @NgModule as shown...

import { PeopleListComponent } from './people-list/people-list.component';

@NgModule({
  imports:      [ BrowserModule],
  declarations: [ AppComponent,PeopleListComponent ],  //<<===here
  providers:    [],      
  bootstrap:    [ AppComponent ]
})

您可以从 AppComponent<的 @Component 中删除 directives:''/code>
