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

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。
