Question

Webpack无法通过 angular-router-loader 找到我试图延迟加载的模块。

我使用以下内容：
Webpack 2.2.1
Angular 5.2
angular-router-loader 0.8.2

通过npm安装 angular-router-loader ，并将加载器添加到我的 webpack config ::

    import itertools
    import matplotlib.pyplot as plt   
    A=['Dog','Cat','Fish','Bird']
    B=[26,39,10,20]
    lists = sorted(itertools.izip(*[A, B]))
    new_x, new_y = list(itertools.izip(*lists))
    fig=plt.figure()
    ax1 = fig.add_subplot(1,1,1)
    ax1.bar(new_x, new_y )
    ax1.set_xticklabels(new_x)
    plt.title("Animals")
    plt.show()

项目布局如下：

       {
            test: /\.ts$/,
            use: ['awesome-typescript-loader', 'angular2-template-loader'],
            exclude: [/\.(spec|e2e)\.ts$/]
        },
        {
            test: /\.(ts|js)$/,
            loaders: [
              'angular-router-loader'
            ]
        },

在 app.routing.ts ：

app/
  - app.routing.ts
  authenticated/
    property/
      - property.module.ts
      setup/
         - propertysetup.component.ts

property.module.ts ：

const appRoutes: Routes = [
  {path: 'property', canActivate: [AuthGuard],
    loadChildren: './authenticated/property/property.module#PropertyModule'
  }
];

当我启动webpack dev服务器时，我可以在控制台中看到 angular-router-loader 正在替换 app的 loadChildren 部分中定义的字符串。 routing.ts ：

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { Routes, RouterModule } from '@angular/router';
import { PropertySetupComponent } from './setup/propertysetup.component';

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

@NgModule({
  imports: [
    RouterModule.forChild(routes),
    CommonModule
  ],
  exports: [
    RouterModule
  ],
  declarations: [
    PropertySetupComponent
  ]
})
export class PropertyModule { }

但是我从webpack收到以下警告：

[angular-router-loader]: --DEBUG--
[angular-router-loader]: File: e:\eclipse_workspace\projectNG\projectFrontend\src\app\app.routing.ts
[angular-router-loader]: Original: loadChildren: './authenticated/property/property.module#PropertyModule'
[angular-router-loader]: Replacement: loadChildren: function() { return new Promise(function (resolve, reject) {  (require as any).ensure([], function (require:
any) {    resolve(require('.\\authenticated\\property\\property.module')

然后，当我尝试在浏览器中转到路径（http://localhost:3000/#/property/setup）时，我从浏览器控制台收到以下堆栈跟踪错误：

WARNING in ./src/app/app.routing.ts
44:84-91 Critical dependency: require function is used in a way in which dependencies cannot be statically extracted

我尝试用绝对路径替换 loadChildren 中的模块路径。 E.g。

 ERROR Error: Uncaught (in promise): Error: Cannot find module "."
    Error: Cannot find module "."
        at webpackMissingModule (eval at 903 (app.js:1618), <anonymous>:44:129)
        at eval (eval at 903 (app.js:1618), <anonymous>:44:208)
        at new ZoneAwarePromise (eval at <anonymous> (polyfills.js:4031), <anonymous>:875:29)
        at loadChildren (eval at 903 (app.js:1618), <anonymous>:44:44)
        at RouterConfigLoader.loadModuleFactory (eval at <anonymous> (vendor.js:156), <anonymous>:4647:109)

但是我从webpack得到完全相同的警告，并且如上所述在浏览器控制台中出错我想我已经从这里正确地遵循了安装/使用说明：https://github.com/brandonroberts/angular-router-loader

任何建议/帮助都非常感激。
