找不到模塊延遲預加載角度路由

Question

我已經看過所有關於此的SO問題，但仍然無法解決。

我正在預加載模塊，但出現錯誤：

錯誤錯誤：未捕獲（承諾）：錯誤：找不到模塊'./results.results.module'錯誤：找不到模塊'./results.results.module'在：4200 / main.js：48：11 [角度]

我已經對拼寫進行了三重檢查，甚至制作了一個小應用程序嘗試重新創建它，但是它運行良好，我不確定自己做錯了什么。 不幸的是，我不能發布一個真實的機密示例。

AppRoutingModule

import { NgModule } from '@angular/core';
import { PlanComponent } from 'app/plan/plan.component';
import { MaintenanceComponent } from './maintenance/maintenance/maintenance.component';
import { Routes, RouterModule, PreloadAllModules } from '@angular/router';

const appRoutes: Routes = [
    { path: '', redirectTo: '/plan', pathMatch: 'full' },
    { path: 'plan', component: PlanComponent },
    { path: 'maintenance', component: MaintenanceComponent },

    // this is the failing module
    { path: 'results', loadChildren: './results/results.module#ResultsModule' },
];

@NgModule({
    imports: [
        RouterModule.forRoot(appRoutes, {
            preloadingStrategy: PreloadAllModules
        })
    ],
    exports: [RouterModule]
})
export class AppRoutingModule {}

的AppModule

import { NgModule, Injector } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
import { AppRoutingModule } from 'app/app-routing.module';

... other components not including the lazy loaded module

...
imports: [
        BrowserModule,
        AppRoutingModule,
        FormsModule,
        HttpModule,
        BrowserAnimationsModule,
        SharedModule.forRoot(),
        MaintenanceModule
]
...

預載路由模塊

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

... component imports

import { Routes, RouterModule } from '@angular/router';

const resultsRoutes: Routes = [
    {
        path: '', component: ResultsComponent, children: [
            { path: 'featurechild', component: featureChildComponent }
        ]
    },
];

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

預裝模塊

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

... other component imports

import { ResultsRoutingModule } from './results-routing.module';

...
imports: [
    CommonModule,
    ResultsRoutingModule,
    FormsModule,
    SharedModule,
...
export class ResultsModule {}

Answer 1

有時ng無法檢測到某些原因。

您可以再次運行命令嗎

ng serve

如果通過npm命令運行，則

npm start
