请帮忙解决此问题。不明白究竟是什么问题。

下面是index.ts，我在引导我的应用程序。

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 })]);

您必须在 NativeScriptRouterModule 内输入main.ts文件中的内容。

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),
    ],
})

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