延迟加载Angular 5错误:$$ _ lazy_route_resource延迟递归

问题描述

我正在使用角度cli AoT编译.当我尝试按照以下 教程 制作延迟加载组件时，出现以下错误:

I'm using angular cli AoT compilation.When I try to make a lazy load component following this tutorial, I got the error below:

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

这是我的代码的一部分:

Here are part of my codes:

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.您可以在此处找到它.

I already report it as an Angular-cli Issue. You can find it here.

有没有遇到过相同问题并找到解决方案的人?

Is there anyone who experienced with the same issue and found a solution for this?

建议的解决方案: https://github.com/gdi2290/angular-starter/issues/1936 :

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

推荐答案

我使用您发布的GitHub代码克隆并复制了该问题.为了修复，您的@ angular/cli global和devDependencies软件包必须位于1.7.2

I cloned and reproduced the issue using your posted GitHub code. In order to fix, your @angular/cli global and devDependencies packages must be at 1.7.2

npm remove -g @angular/cli
npm install -g @angular/[email protected]
npm remove @angular/cli
npm add @angular/[email protected] --save-dev

现在，您的devDependencies中的@ angular/cli包与全局版本匹配，并且已将其设置为1.7.2，以解决该问题.

Now the @angular/cli package in your devDependencies matches the global version and it is set to 1.7.2 where that issue is resolved.
