Angular 2 - 未找到traceur

Question

我收到一个奇怪的错误：

GET http://localhost:3000/app/traceur 404 (Not Found)

我的应用程序构建，但是当我尝试继续它时，它不会加载并且此错误在控制台中出现。出于某种原因，当我删除此组件的directives部分时，错误消失了：

import { Component, OnInit } from '@angular/core';
import { ContextService } from './../../services/ContextService';
import { Herd } from './../../classes/shared/herd';
import { Animal } from './../../classes/shared/animal';
import { CalendarWidget } from './../../classes/calendar';
import { Schedule } from 'primeng/components/schedule/schedule.d.ts';
import { Router, ROUTER_DIRECTIVES } from '@angular/router-deprecated';

@Component({
    selector: 'dash',
    templateUrl: '/templates/Dash/dash.html',
    providers: [CalendarWidget],
    directives: [Schedule] // when I remove this line then it works
})

export class DashComponent implements OnInit
{
    public animals: Animal[];
    public constructor(public router: Router, public context: ContextService, public calendar: CalendarWidget) {}

    ngOnInit()
    {
        this.animals = this.context.herd.GetAnimals();
        this.calendar.events = this.context.user.getEvents(1); 
    }

    onSelect(animal: Animal) {
        this.router.navigate( ['AnimalDetail', { id: animal.ID }] );
    }
} 

任何人都知道发生了什么？过去似乎有一些人遇到过这个错误，但没有一个修复工作对我有用。
