找不到自定义模块

core.js:18374错误:未捕获(承诺中):错误:找不到模块“”/orders/orders.module'
错误:找不到模块“”/orders/orders.module'

我不知道为什么会发生这样的事情 .../src/app/orders/orders.module.ts .../src/app/orders 目录和其中的多个组件。为了实现这些模块,我这样做了

% mv src/app/orders orders
% ng g m orders --routing
% mv orders/* src/app/orders

然后我删除了所有的路线 app-routing.module.ts

{
    path: 'orders',
    loadChildren: './orders/orders.module#OrdersModule'
},
{
    path: '',
    redirectTo: 'orders',
    pathMatch: 'full'
}

然后 orders-routing.module.ts 看起来是这样的:

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

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

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

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

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

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

您可以看到文件存在于适当的位置。
