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

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 {}
答
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]
})
