在App中使用ng2引導程序時出錯

Question

我是Angular 2的新手，嘗試在我的應用程序中使用ng2-bootstrap。 我遵循了有關angular-cli入門的說明。 以下是我的app.module.ts和angular-cli.json文件。

當我嘗試在其中一個組件上使用時，出現5次以下錯誤：

例外：未捕獲（承諾）：錯誤：模板解析錯誤：'accordion'不是已知元素：1.如果'accordion'是Angular組件，請驗證它是否屬於此模塊。 2.如果“ accordion”是Web組件，則將“ CUSTOM_ELEMENTS_SCHEMA”添加到該組件的“ @ NgModule.schemas”以禁止顯示此消息。

我想念什么？ 我需要采取什么步驟來整合ng2-bootstrap？

app.module.ts

import { NgModule }                     from '@angular/core';
import { BrowserModule }                from '@angular/platform-browser';
import { LocationStrategy,
         HashLocationStrategy,CommonModule }         from '@angular/common';

import { AppComponent }                 from './app.component';
import { NAV_DROPDOWN_DIRECTIVES }      from './shared/nav-dropdown.directive';

import { ChartsModule }                 from 'ng2-charts/ng2-charts';
import { SIDEBAR_TOGGLE_DIRECTIVES }    from './shared/sidebar.directive';

import { AsideToggleDirective }         from './shared/aside.directive';
import { BreadcrumbsComponent }         from './shared/breadcrumb.component';
import { DashboardModule } from './dashboard/dashboard.module';
import { SupplierDataService } from './services/supplier-data.service';
import { Angular2FontawesomeModule} from 'angular2-fontawesome';
import { AccordionModule } from 'ng2-bootstrap/accordion';


// Routing Module
import { AppRoutingModule }             from './app.routing';

// Layouts
import { FullLayoutComponent }          from './layouts/full-layout.component';

// Http
import { HttpModule } from '@angular/http';

@NgModule({
    imports: [
        BrowserModule,
        CommonModule,
        AppRoutingModule,
        ChartsModule,
        DashboardModule,
        Angular2FontawesomeModule,
        HttpModule,
        AccordionModule.forRoot()
    ],
    declarations: [
        AppComponent,
        FullLayoutComponent,
        NAV_DROPDOWN_DIRECTIVES,
        BreadcrumbsComponent,
        SIDEBAR_TOGGLE_DIRECTIVES,
        AsideToggleDirective
    ],
    providers: [SupplierDataService,
    {
        provide: LocationStrategy,
        useClass: HashLocationStrategy
    }],
    bootstrap: [ AppComponent ]
})
export class AppModule { }

我認為您錯過了必須在angular-cli.json中的腳本中導入的bootstrap.js文件。

 "scripts": [
        "../node_modules/chart.js/dist/Chart.bundle.min.js",
        "../node_modules/chart.js/dist/Chart.min.js",
        "../node_modules/bootstrap/dist/js/bootstrap.js"
      ]
