在Angular2中获取异常EXCEPTION：没有PlatformLocation的提供者？

Question

在浏览器控制台中查看例外情况。

请帮忙解决这个问题。不完全理解什么是问题。

下面是index.ts我引导我的应用程序。

import {bootstrap} from "@angular/platform-browser-dynamic"; 
import {enableProdMode,provide} from "@angular/core"; 
import {ROUTER_PROVIDERS} from "@angular/router"; 
import {HTTP_PROVIDERS} from "@angular/http"; 
import {MyAppComponent} from "./components/MyApp.component"; 
import {SimpleExpiry} from 'ng2-idle/simpleexpiry'; 

import {APP_BASE_HREF, LocationStrategy, HashLocationStrategy} from "@angular/common"; 

enableProdMode(); 
bootstrap(<any>MyAppComponent, [ROUTER_PROVIDERS, HTTP_PROVIDERS,SimpleExpiry, 
provide(APP_BASE_HREF, { useValue: "/" }), 
provide(LocationStrategy, { useClass: HashLocationStrategy })]);

你必须失去NativeScriptRouterModule内进口的main.ts文件。

import { NativeScriptRouterModule } from "nativescript-angular/router"; 
import { NativeScriptFormsModule } from "nativescript-angular/forms"; 

@NgModule({ 
    declarations: [ 
     AppComponent, 
     routableComponents, 
    ], 
    bootstrap: [AppComponent], 
    imports: [ 
     NativeScriptModule, 
     NativeScriptFormsModule, 
     NativeScriptRouterModule, 
     NativeScriptRouterModule.forRoot(routes), 
    ], 
})
