Nativescript/angular2：没有applicationRef的提供者！部署后出现错误

我试图运行一个非常简单的nativescript/angular2应用程序，它似乎构建良好，但应用程序被部署到android（genymotion）模拟器后，我收到以下错误消息。所以它看起来像棱角不是自举？不知道为什么这是...任何想法我做错了什么？Nativescript/angular2：没有applicationRef的提供者！部署后出现错误

错误消息：

我main.ts文件是否有帮助：

import { platformNativeScriptDynamic } from "nativescript-angular/platform"; 


import { AppModule } from "./app.module"; 



platformNativeScriptDynamic().bootstrapModule(AppModule);

和我app.module.ts：

import { NgModule } from "@angular/core"; 
import { NativeScriptFormsModule } from "nativescript-angular/forms"; 
import { NativeScriptModule } from "nativescript-angular/platform"; 
import { NativeScriptRouterModule } from "nativescript-angular/router"; 

import { AppComponent } from "./app.component"; 
import {routes, navigatableComponents } from "./app.routing"; 

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

从删除您的括号imports in ngModule，它应该是一个模块数组。像这样：

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