我跟着this教程向我的应用添加了延迟加载。一切正常，本地服务器上的罚款，但是当我发表我的应用程序，我得到错误模块不能found.I我采用了棱角分明的编译器Plugin.Here是我的package.json "dependencies": { "@angular/animations": "^5.0.0", "@angular/cdk": "^5.0.0", "@angular/common": "^5.0.0", "@angular/compiler": "^5.0.0", "@angular/compiler-cli": "^5.0.0", "@angular/core": "^5.0.0", "@angular/forms": "^5.0.0", "@angular/http": "^5.0.0", "@angular/material": "^5.0.0", "@angular/material-moment-adapter": "^5.0.0", "@angular/platform-browser": "^5.0.0", "@angular/platform-browser-dynamic": "^5.0.0", "@angular/platform-server": "^5.0.0", "@angular/router": "^5.0.0", "@ngtools/webpack": "^1.9.0", "@types/webpack-env": "1.13.0", "angular-router-loader": "^0.8.0", "angular2-infinite-scroll": "^0.3.5", "angular2-template-loader": "0.6.2", "aspnet-prerendering": "^3.0.1", "aspnet-webpack": "^2.0.1", "awesome-typescript-loader": "3.2.1", "bootstrap": "^3.3.7", "bootstrap-select": "^1.12.4", "css": "2.2.1", "css-loader": "0.28.4", "es6-shim": "0.35.3", "event-source-polyfill": "0.0.9", "expose-loader": "0.7.3", "extract-text-webpack-plugin": "2.1.2", "file-loader": "0.11.2", "font-awesome": "^4.7.0", "hammerjs": "^2.0.8", "html-loader": "0.4.5", "isomorphic-fetch": "2.2.1", "jquery": "^3.2.1", "json-loader": "0.5.4", "moment": "^2.19.4", "ng2-auto-complete": "^0.12.0", "ngx-bootstrap": "^1.9.3", "preboot": "4.5.2", "raw-loader": "0.5.1", "reflect-metadata": "0.1.10", "rxjs": "^5.5.2", "select2": "^4.0.4", "style-loader": "0.18.2", "to-string-loader": "1.1.5", "typescript": "2.4.2", "url-loader": "0.5.9", "webpack": "2.5.1", "webpack-hot-middleware": "2.18.2", "webpack-merge": "4.1.0", "zone.js": "0.8.12" }无法在生产中的Angular 5 + ASP.NET Core 2应用中添加延迟加载

我也试图加载我的部件用difrent办法像这个：

path: 'hero', loadChildren:() => { 
    return Promise.resolve(require('./components/hero/hero.module')['HeroModule']); 
}

但是然后我得到错误对象类型的索引签名隐式地有一个'任何'类型。

回答：

我创建了4个模块，所有都是你必须删除您从app.module.ts文件要延迟加载的模块角
第一件事就是懒加载，这里是例子，我懒加载主页模块
app.module.ts

import { NgModule} from '@angular/core'; 
//modules 
    import {BrowserAnimationsModule} from '@angular/platform-browser/animations'; 
    import { BrowserModule } from '@angular/platform-browser'; 
    //routing modules 
    import { AppRoutingModule } from './app-routing.module'; 
    @NgModule({ 
    declarations: [ ], 
    imports: [ 
    BrowserModule, 
    BrowserAnimationsModule, 
    AppRoutingModule, ], 
     bootstrap: [AppComponent] 
     }) 
    export class AppModule {}

的MODUL Ë要延迟加载会在应用程序的路由模块
应用路由-module.ts

import { NgModule } from '@angular/core'; 
import { Routes, RouterModule } from '@angular/router'; 
const routes: Routes = [ 
{ path: "", component: LandingComponent }, 
{ 
    path: "homepage", 
    loadChildren: "./homepage/homepage.module#HomePageModule" 
}, 
]; 
@NgModule({ 
    imports: [RouterModule.forRoot(routes)], 
    exports: [RouterModule] 
    }) 
export class AppRoutingModule { }

负载孩子是我们使用属性时，我们要延迟加载任何模块中我们的应用程序和#HomePageModule是我想偷懒加载
要检查模块模块的名称一直是懒加载，当你建立你的应用程序的角度，它会给你一块这样

chunk {homepage.module} homepage.module.chunk.js, 
homepage.module.chunk.js.map() 6.41 kB [rendered] 
chunk {inline} inline.bundle.js, inline.bundle.js.map (inline) 5.83 kB 
[entry] [rendered] 
chunk {polyfills} polyfills.bundle.js, polyfills.bundle.js.map 
(polyfills) 215 kB [initial] [rendered] 
chunk {styles} styles.bundle.js, styles.bundle.js.map (styles) 177 kB 
[initial] [rendered] 
chunk {vendor} vendor.bundle.js, vendor.bundle.js.map (vendor) 5.31 MB 
[initial] [rendered]
