错误:无法解析TypeDecorator的所有参数:Angular 2 RC-6

Question

我有这个错误超过一天,我不知道为什么.

app.module

import {NgModule} from "@angular/core";
import {BrowserModule} from "@angular/platform-browser";
import {AppComponent} from "./app.component";
import {FormsModule} from "@angular/forms";
import {LoginComponent} from "./Login/login";
import {LoginService} from "./Login/login.service";

@NgModule({
    imports: [BrowserModule, FormsModule],

    declarations: [AppComponent,
        LoginComponent],

    providers:[LoginService],

    bootstrap: [AppComponent]
})
export class AppModule {

}

app.component.ts

import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    template: '<login></login>'
})
export class AppComponent {

}

login.model.ts

export class LoginModel{

    private userName: string;
    private password: string;

    constructor(userName: string='', password: string=''){
        this.userName = userName;
        this.password = password;
    }

}

login.ts

import {Component} from '@angular/core';
import {LoginModel} from "./login.model";
import {LoginService} from "./login.service";

@Component({
    moduleId: module.id,
    selector: 'login',
    templateUrl:'./login.html',
    styleUrls:['../css/styles.css'],

})

export class LoginComponent{

    login:LoginModel = new LoginModel();

    constructor(public loginService:LoginService){

    }

    onSubmit() {
        this.loginService.output();
    }

login.service

import {Injectable, Inject} from '@angular/core';
import {Http, Response} from '@angular/http';
import {Observable} from 'rxjs/Rx';

@Injectable
export class LoginService {

    output(){
        console.log("You are in the service output class...");
    }
}

目前我只是想让应用程序编译,所以我可以创建路由和服务.这是项目的重点,但我一直在打墙.任何建议将不胜感激.

在我的情况下,login.service.ts缺少()inInjectable()
