在IE10中升级到Angular2 RC5后没有提供PlatformRef错误

我刚升级到Angular2 RC5。该应用程序在所有浏览器异常IE10中加载正常。我得到一个例外“没有PlatformRef的提供者!”当我引导应用程序时。在RC4中一切都运行良好。我在网上看到了一些关于这个例外的帖子,但它们都与Meteor有关。我不使用流星。我的项目源自AngularSeed(我手动更新到RC5的先前版本)。有关如何解决此问题的任何想法?谢谢!

在IE10中,我收到此错误:

No provider for PlatformRef!  
{
  [functions]: ,
  context: <Permission denied>,
  injectors: [ ],
  keys: [ ],
  message: "No provider for PlatformRef!",
  name: "Error",
  stack: undefined,
  Symbol()_m.sovohbnexgu: undefined,
  Symbol()_n.sovohbnexgu: undefined,
  Symbol()_o.sovohbnexgu: undefined,
  Symbol(rxSubscriber)_p.sovohbnexgu: undefined
}

main.ts:

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule }              from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

的AppModule:

import { provide, NgModule, ExceptionHandler } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule } from '@angular/router';
import { HttpModule } from '@angular/http';
import { FormsModule } from '@angular/forms';

import { AppComponent } from './components/app/app.component';
import { AppExceptionHandler } from './app.exceptionhandler';
import { AppRoutes } from './app.routes';
import { LogService, ... } from './services/';

@NgModule({
    declarations: [AppComponent, ...],
    imports: [BrowserModule,
              RouterModule.forRoot(AppRoutes),
              HttpModule,
              FormsModule],
    providers: [provide(ExceptionHandler, { useClass: AppExceptionHandler }), LogService, ...],
    bootstrap: [AppComponent],
})
export class AppModule { }

依赖版本:

  • “@ angular / common”:“2.0.0-rc.5”,
  • “@ angular / compiler”:“2.0.0-rc.5”,
  • “@ angular / core”:“2.0.0-rc.5”,
  • “@ angular / forms”:“0.3.0”,
  • “@ angular / http”:“2.0.0-rc.5”,
  • “@ angular / platform-b​​rowser”:“2.0.0-rc.5”,
  • “@ angular / platform-b​​rowser-dynamic”:“2.0.0-rc.5”,
  • “@ angular / router”:“3.0.0-rc.1”,
  • “es6-module-loader”:“^ 0.17.8”,
  • “core-js”:“^ 2.4.0”,
  • “rxjs”:“5.0.0-beta.6”,
  • “systemjs”:“0.19.27”,
  • “zone.js”:“0.6.13”,

编辑:如果我尝试将PlatformRef添加到@NgModule导入,我会收到此错误:

shims.js?1472473326356:4 Uncaught TypeError: Cannot read property 'type' of null(anonymous function)

我在IE上获得这个堆栈:

我认为您应该从PlatformRef导入@angular/core并将imports NgModule配置添加到AppModule文件后检查相同内容。

解决方案是从依赖项中删除es6-shim。现在工作正常。
