Question

我正在尝试 Angular Lazy Load ，我有一个奇怪的错误，而其中一条路线完美无缺，而另一条（类似的结构和实现）给我一个错误。这是我的简单代码：

app.module.ts

中的

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';


import { AppComponent } from './app.component';

const routes: Routes = [
  {
    path: 'customers',
    loadChildren: 'app/customers/customers.module#CustomersModule'
  },
  {
    path: 'orders',
    loadChildren: 'app/orders/orders.module#OrdersModule'
  },
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
];
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    RouterModule.forRoot(routes)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

在orders.module.ts

中的

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { OrdersRoutingModule } from './orders-routing.module';
import { OrderListComponent } from './order-list/order-list.component';

@NgModule({
  imports: [
    CommonModule,
    OrdersRoutingModule
  ],
  declarations: [OrderListComponent]
})
export class OrdersModule { }

并在orders-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { OrderListComponent } from './order-list/order-list.component';

const routes: Routes = [
  {
    path: '',
    component: OrderListComponent
  }
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class OrdersRoutingModule { }

当我转到localhost:4200/orders 时，一切正常，即没有错误，延迟加载功能按预期工作。

在customers.module.ts

中的

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { CustomersRoutingModule } from './customers-routing.module';
import { CustomerListComponent } from './customer-list/customer-list.component';

@NgModule({
  imports: [
    CommonModule,
    CustomersRoutingModule
  ],
  declarations: [CustomerListComponent]
})
export class CustomersModule { }

并在customers-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { CustomerListComponent } from './customer-list/customer-list.component';

const routes: Routes = [
  {
    path: '',
    component: CustomerListComponent
  }
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class CustomersRoutingModule { }

但是当我转到localhost:4200/customers时，它会给我错误：

Error: Component CustomerListComponent is not part of any NgModule or the module has not been imported into your module.

为什么这只发生在customers路线上？如何解决这个问题？

组件CustomerListComponent不是任何NgModule的一部分，或者模块尚未导入到您的模块中
