角为2的电子有问题

Question

main.desktop.ts

import { UniversalModule, isBrowser, isNode, REQUEST_URL, ORIGIN_URL } from 'angular2-universal';

import { App } from './app/app';


@NgModule({
  bootstrap: [ App ],
  declarations: [
    App
  ],
  imports: [
    routing,
    // Univesal module
    UniversalModule, // BrowserModule, HttpModule, and JsonpModule are included
  ],
  providers: [
  ],
  entryComponents: [
    App
  ]
})

desktop.ts

 // the polyfills must be the first thing imported
 import 'angular2-universal-polyfills';
 import 'ts-helpers';
 import './__workaround.browser.ts';

// Angular 2
import { enableProdMode } from '@angular/core';
import { platformUniversalDynamic } from 'angular2-universal/browser';
import { bootloader } from '@angularclass/bootloader';

import { load as loadWebFont } from 'webfontloader';

// enable prod for faster renders
enableProdMode();

import { MainModule } from './main.desktop';

const platformRef = platformUniversalDynamic();

// on document ready bootstrap Angular 2
export function main() {
  // Load fonts async
  // https://github.com/typekit/webfontloader#configuration
  loadWebFont({
    google: {
      families: ['Droid Sans']
    }
  });

  return platformRef.bootstrapModule(MainModule);
}

// support async tag or hmr
bootloader(main);

我收到一个无法解决的错误。请帮忙..。!!！这和angular2-universal有关吗？

注：

1.如有需要，请让我知道我会提供的。2.我得到以下错误；

未处理的承诺拒绝:参数'url‘必须是字符串，而不是未定义的；区域：；任务: Promise.then；值: TypeError:参数'url’必须是字符串，而不是未定义的(…)TypeError:参数'url‘必须是字符串，而不是未定义的Url.parse (url.js:90:11) at urlParse (url.js:84:5) at Object.urlResolve as resolve

当我评论angular2-universal时，我得到了；

未处理的承诺拒绝:不提供ApplicationRef！；Zone：；Task: Promise.then；Value: NoProviderError Error: NoProviderError！at NoProviderError.Error (本机) at NoProviderError.BaseError作为构造函数

我自己解决了这个问题，只是将import { UniversalModule, isBrowser, isNode, REQUEST_URL, ORIGIN_URL } from 'angular2-universal';更改为import { UniversalModule, isBrowser, isNode } from 'angular2-universal/browser';，并在索引页(即<base href="./"> )中添加基本href。
