角2リリース "予期しない値 'モジュールによってインポートされた' ElementRef '

Question

私は角2のリリースにアップグレードし、ElementRefを使用しようとしています。 Angular2 RC5 error:zone.js: Unhandled Promise rejection: No provider for ElementRefはそう私は私のコードを変更：最初に、ここで指定したように私はエラーAngular2 RC5 error:zone.js: Unhandled Promise rejection: No provider for ElementRefを得た

import { NgModule, CUSTOM_ELEMENTS_SCHEMA, ElementRef }  from '@angular/core'; 
@NgModule({ 
    declarations: [DashboardComponent, WidgetBankComponent, DataTableDirectives, OrderBy], 
    exports: [DashboardComponent, WidgetBankComponent], 
    imports: [BrowserModule, HttpModule, FormsModule, ChartsModule, ElementRef], 
    providers: [ChartService, GridService, WidgetsControlService, GridViewService, ApplicationSettingsService, DataService, ToolsService, LocalStorageService, RuntimeCompiler, COMPILER_PROVIDERS, NgGrid, NgGridItem], 
    schemas: [CUSTOM_ELEMENTS_SCHEMA] 
}) 

、今私は、エラー(SystemJS) Unexpected value 'ElementRef' imported by the module 'DashboardModule'

任意のアイデアを取得していますか？

ありがとうございます！

EDIT

以下の答えで推奨修正を行なったし、今、このエラーを持っている - ここで完全なエラーがある - 私はこのエラーからプロバイダを供給する必要がある場所伝える方法はありますか？

Answer 1

あなたがそれを必要と個々のコンポーネントレベルでそれを使用しています。

import { ElementRef } from '@angular/core'; 
@Component({ 
.... 
}) 
export class DashboardComponent{ 
    constructor(private el:ElementRef){} 
} 

Answer 2

imports配列からElementRefを削除し、providersの配列に貼り付けしよう：

import { NgModule, CUSTOM_ELEMENTS_SCHEMA, ElementRef } from '@angular/core'; 
@NgModule({ 
    declarations: [DashboardComponent, WidgetBankComponent, DataTableDirectives, OrderBy], 
    exports: [DashboardComponent, WidgetBankComponent], 
    imports: [BrowserModule, HttpModule, FormsModule, ChartsModule], 
    providers: [ChartService, GridService, WidgetsControlService, GridViewService, ApplicationSettingsService, DataService, ToolsService, LocalStorageService, RuntimeCompiler, COMPILER_PROVIDERS, NgGrid, NgGridItem, ElementRef], 
    schemas: [CUSTOM_ELEMENTS_SCHEMA] 
})
