Question

当我尝试加载我的角度2.0应用程序时，我收到以下错误：（索引）：21错误：错误：模块'AppModule'导入的意外值'[object Object]'

import { ModuleWithProviders }  from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { searchComponent }      from './search.Component'; 
import { landingComponent }     from './landing.Component'; 

export const routes: Routes = [
{
    path: '',
    component: searchComponent
},
{
    path: 'search',
    component: searchComponent
}];
export const routedComponents = [searchComponent, landingComponent];
export const routing: ModuleWithProviders = RouterModule.forRoot(routes);

的AppModule

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }   from '@angular/forms';
import { HttpModule }    from '@angular/http';
import { landingComponent }              from './landing.Component'; 
import { searchComponent }               from './search.Component'; 
import { routes, routedComponents }      from './app.routing';
import { homeScript }                    from './Services/homeScript';

@NgModule({
imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    routes
],
declarations: [
    landingComponent,
    searchComponent,
    routedComponents
],
providers: [
    homeScript
],
bootstrap: [landingComponent]

})
export class AppModule { }

键入用于启动的脚本

///<reference path="./../typings/globals/core-js/index.d.ts"/>
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './appModule';

platformBrowserDynamic().bootstrapModule(AppModule)
  .then(success => console.log(`Bootstrap success`))
  .catch(error => console.log('GUY  ' + error));

如果我从导入中移除“路线”，则会加载着陆页但没有任何错误。我怀疑路由中的错误，因为如果我删除了 appModule中的'routes'正确加载着陆页。我试了很多变化，但我无法确定问题的原因。任何帮助将不胜感激。

Answer 1

问题是您将routedComponents设置为声明的一部分。由于这不是指令，组件或管道，因此您会收到此异常。从模块声明数组中删除 routedComponents ，它将解决您的问题。

Answer 2

只需删除＆＃34;路线＆＃34;从导入数组并添加＆＃34;路由＆＃34;对此：

imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    routing
]

  app.menurouting.ts
export  const menurouting:Routes=[{path:'',redirectTo:'menu',pathMatch:'full'},
          {path:'restarenttype',component:RestaurantTypeComponentComponent},
           {path:'table',component:TablelayoutComponent},
          {path:'blog',component:ViewmenuComponent},
        ];
        export  const routes:ModuleWithProviders=RouterModule.forRoot(menurouting)

    app.module.ts

    import {routes} from './app.menurouting';

    @NgModule({
      declarations: [
        AppComponent,
        LoginComponentComponent,
        TablelayoutComponent,
        ViewmenuComponent,
        RestaurantTypeComponentComponent
      ],
      imports: [
        BrowserModule,
        routes
      ],
      providers: [],
      bootstrap: [AppComponent]
    })
    export class AppModule { }

确保模块已正确定义为@NgModule并注意您的课程拼写，以确保它们匹配。

请注意，这是Angular 2的最终版本。
