Angular2版本RC.6“指令”在@Component错误中

Question

我正在使用Angular2并从官方网站下载了package.json。 当我试图在@Component装饰器中使用“指令”时，我收到此错误。

我附上了我的代码错误：

[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：

        }

Answer 1

简单...

问题在于directives: ''

作为一个数组，它应该是directives: [ ]

更新 ：在RC6 或更高版本中，您有@NgModule 。 在RC6 或更高版本中，您必须声明要在@NgModule使用的pipes和directives ，如图所示......

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

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

您可以从AppComponent @Component中删除directives:''

@Component directives和pipes @Component角度RC6中。 在https://stackoverflow.com/questions/39410417/how-to-import-component-into-another-root-component-in-angular-2上查看我的答案
