ListingComponent is not part of any NgModule or the module has not
been imported into your module

此错误表示我没有将ListingComponent添加到ngModule,但它作为声明存在.

在app.module中,我将所有组件都作为声明.我还导入了我的路由组件.路由组件有一个名为listing.routes的子路由组件.

这是我的app.module.ts：

import {NgModule,CUSTOM_ELEMENTS_SCHEMA,ReflectiveInjector  } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {FormsModule,FormBuilder} from '@angular/forms';
import { NgClass,NgStyle} from '@angular/common';
import { AppComponent }   from './app.component';
import {routing} from './app.routes';
import {ListingModule} from './components/listing/listingmodule';
import {ListingComponent} from './components/listing/listing.Component';

@NgModule({
    imports: [BrowserModule,routing],providers: [],declarations: [AppComponent,ListingComponent,ListingModule],bootstrap: [AppComponent]
})
export class AppModule {

}

这是我的app.routes.ts(我作为路线导入)：

import { ModuleWithProviders }  from '@angular/core';
import { Routes,RouterModule } from '@angular/router';
import {ListingRoutes} from './components/listing/listing.routes';
import {SplashComponent} from './components/splash/splash.component';

export const appRoutingProviders: Routes = ([
    { path: '',component: SplashComponent },{ path: 'login',...ListingRoutes
]);

export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutingProviders);

这是我的listing.routes.ts：

import { ModuleWithProviders } from '@angular/core';
import { Routes,RouterModule } from '@angular/router';
import {ListingModule} from './repairreturnmodule';
import {ListingComponent} from '../listing/listing.component';


export const ListingRoutes: Routes = [
    {
        path: '',component: ListingModule,children: [
            { path: 'listing',component: ListingComponent},]
    }
];

export const ListingRouting: ModuleWithProviders = RouterModule.forChild(ListingRoutes);

我错过了什么吗？
