angular - 延迟加载 Angular 5 错误 : $$_lazy_route_resource lazy recursive

Question

我正在使用 angular cli AoT 编译。当我尝试按照此 tutorial 制作延迟加载组件时，我得到以下错误:

ERROR Error: Uncaught (in promise): TypeError: __webpack_require__.e is not a function

这是我的部分代码:

app-routing.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  { path: 'listes', loadChildren: 'app/component/list/list.module#ListModule'}
];

@NgModule({
  imports: [
    RouterModule.forRoot(routes)
  ],
  declarations: [],
  exports: [ RouterModule ]
})
export class AppRoutingModule { }

list-routing.module.ts

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

import { ListComponent } from './list.component';

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

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

list.module.ts

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

import { ListRoutingModule } from './list-routing.module';

import { ListComponent } from './list.component';

@NgModule({
  imports: [
    CommonModule,
    ListRoutingModule
  ],
  declarations: [ ListComponent ]
})
export class ListModule { }

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { HeaderComponent } from './component/header/header.component';
import { FooterComponent } from './component/footer/footer.component';
import { AppRoutingModule } from './app-routing.module';
import { DetailModule } from './component/detail/detail.module';
import { HomeComponent } from './component/home/home.component';


@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent,
    FooterComponent,
    HomeComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {}

我已经将其报告为 Angular-cli 问题。你可以找到它here .

有没有遇到同样问题并找到解决方案的人？

Related bug: Angular 5 with Angular cli non-lazy loading modules in the router (Not solved yet).

Proposed solution: https://github.com/gdi2290/angular-starter/issues/1936:

{ path: 'listes', loadChildren: () => ListModule }
// it doesn't do lazy loading

重要信息:

Angular cli: 1.7.0
Angular: 5.2.0

我的问候

Answer 1

我遇到了同样的问题。我解决了只需停止 cli 服务器并启动它。如果您正确完成代码，错误就会消失。
