问题
I just upgraded to Angular2 RC5. The app loads fine in all browsers exception IE10. I get an exception "No provider for PlatformRef!" when I bootstrap the application. Everything worked fine in RC4. I saw some posts on the web about this exception, but they were all related to Meteor. I do not use meteor. My project is derived from AngularSeed (previous version that I updated manually to RC5). Any idea on how to fix this? Thanks!
In IE10, I get this error:
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,

}
main.ts:
import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
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 { }

Edit: If I try to add PlatformRef to the @NgModule imports, I get this error:

回答1:
I think you should check the same after importing PlatformRef
from @angular/core
and adding it to imports
configuration of NgModule
for your AppModule file.
回答2:
The solution was to remove es6-shim from the dependencies. Works fine now.
