延迟加载Angular 5错误:$$ _ lazy_route_resource懒惰递归

Question

我正在使用angular cli AoT编译.当我尝试按照本教程制作延迟加载组件时,我收到以下错误:

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

以下是我的代码的一部分:

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 { }

列表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 {}

我已将其报告为Angular-cli问题.你可以在这里找到它.

是否有人遇到过同样的问题,并为此找到了解决方案？

相关错误: Angular 5与路由器中的Angular cli非延迟加载模块 (尚未解决).

建议的解决方案: 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

致以我的问候

Answer 1

我遇到了同样的问题.我解决了它只是停止cli服务器并启动它.如果您正确完成了代码,则错误消失.

Answer 2

我使用您发布的GitHub代码克隆并重现了该问题.为了修复,你的@ angular/cli global和devDependencies包必须是1.7.2

npm remove -g @angular/cli
npm install -g @angular/cli@1.7.2
npm remove @angular/cli
npm add @angular/cli@1.7.2 --save-dev

现在devDependencies中的@ angular/cli包与全局版本匹配,并且在解决该问题时将其设置为1.7.2.

Answer 3

angular-cli 1.7.x上有一个开放的bug :https://github.com/angular/angular-cli/issues/9488#issuecomment-368871510

降级到1.6.8为我解决了这个问题.

Answer 4

我得到了相同的问题.使用它修复它

 {path:'listes' ,loadChildren: ()=>ListModule} not {path:'listes' ,loadChildren: 'app/component/list/list.module#ListModule'}

Answer 5

请参阅有关1.7.x错误的注释。问题似乎是将延迟加载的模块导入AppModule。删除该导入为我解决了这个问题：https : //github.com/angular/angular-cli/issues/9488#issuecomment-374037802
