【问题描述】:
我刚刚升级到 Angular2 RC5。该应用程序在所有浏览器(IE10 除外)中都能正常加载。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 中一切正常。我在网上看到一些关于这个异常的帖子,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)。关于如何解决这个问题的任何想法?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);
应用模块:
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”,

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 上得到了这个堆栈:
