Question

我试图创建我自己的混合ui-router应用程序，就像它在https://github.com/ui-router/sample-app-angular-hybrid中显示的只有一个区别 - 使用systemjs而不是webpack。

当应用加载时会抛出错误：

zone.js:643 Unhandled Promise rejection: Cannot read property 'when' of undefined ; Zone: <root> ; Task: Promise.then ; Value: TypeError: Cannot read property 'when' of undefined
    at new Resolvable (resolvable.ts:86)

我无法为它创建plunkr，因为测试应用程序非常庞大。也许有人知道什么会产生这个错误？

我的app systemjs.config.js：

(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': '../node_modules/',
      'bower_libs:': 'lib/'
    },
    // map tells the System loader where to look for things

        deps: ['jquery']
      }
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: '../main.js',
        defaultExtension: 'js',
        meta: {
          './*.js': {

        main: './index.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);

Mine angular app模块与示例相同，我的angularjs app模块几乎相同，只是导入部分：

import 'jquery';
import 'lodash';
import * as angular from 'angular';
import 'angular-animate';
import 'angular-sanitize';
import 'angular-resource';
import 'angular-cookies';
import { upgradeModule } from "@uirouter/angular-hybrid";
import uiRouter from '@uirouter/angularjs';
import 'ng-table';
import 'ngInfiniteScroll';
import 'angular-translate';
import 'angular-translate-loader-partial';
import 'ng-file-upload-shim';
import 'ng-file-upload';
import 'ui.bootstrap';
import 'ui.validate';
import 'angucomplete-alt';
import 'ui.layout';
import 'angular-sortable-view';
import 'angular-bootstrap-contextmenu';
import 'palettejs';

目前...... （今天是2017年6月）最新版本的'@uirouter/angular' （@version v1.0.0-beta.7）处于混合模式不要调用其中一个初始部分： servicesPlugin()

要解决此问题，只需在主模块

之前包含这些行

// FIX for the HYBRID
import { servicesPlugin }        from '@uirouter/angular';
servicesPlugin(null);

并继续......

// Our new ng++ module
@NgModule({
  imports: [
    UpgradeModule,
    UIRouterModule,
    UIRouterUpgradeModule,
    UIRouterModule.forChild({ states: states, useHash: true }),
    BrowserModule
  ],
  declarations: [
    ...
  ],
  entryComponents: [
    ...
  ],
  providers: [
    { provide: NgModuleFactoryLoader, useClass: SystemJsNgModuleLoader }
  ]
})
export class NewAppModule {
  ngDoBootstrap() {}
}

无法使用SystemJS启动ui-router混合应用程序
