angular - 错误: Can't resolve all parameters for TypeDecorator: Angular 2 RC-6

Question

这个错误已经发生一天多了，但我不知道为什么。

应用程序模块

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 {

}

登录.model.ts

export class LoginModel{

    private userName: string;
    private password: string;

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

}

登录.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();
    }

登录.服务

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...");
    }
}

目前我只是尝试编译应用程序，以便我可以创建路由和服务。这就是这个项目的重点，但我总是碰壁。任何建议将不胜感激。

Answer 1

在我的例子中，login.service.ts 缺少 Injectable() 中的 ()
