Ionic 2：typescript：typescript：找不到名称'EventStaffLogService'

Question

我遇到此错误。我已安装最新的应用程序脚本。我对打字稿不太了解，但是在我运行更新脚本之前，这已经习惯了。

CLI

$ ionic serve 

Running 'serve:before' npm script before serve

event-sign-in.component.ts 

事件登录in.component.ts

import { Component } from '@angular/core'; 
import { NavController, NavParams, ToastController } from 'ionic-angular'; 
import { EventStaffLogService, EventStaff } from '../shared/'; 

@Component({ 
    templateUrl: 'event-sign-in.component.html', 
    providers: [EventStaffLogService] 
}) 
export class EventSignInComponent { 
    eventStaff: any; 
    eventStaffLogs: Object = { data: [] }; 
    fetchingLogs: Boolean = true; 
    isSignIn: Boolean = false; 

    constructor(
    private navCtrl: NavController, 
    private navParams: NavParams, 
    private eventStaffLogService: EventStaffLogService, 
    public toastController: ToastController 
) { 
    this.eventStaff = navParams.get('eventStaff'); 
    this.getEventStaffLogs(); 
    } 
    ...

刚刚发现的问题。似乎从index.ts文件导入会导致此错误。

从改变我的代码：

import { EventStaffLogService, EventStaff } from '../shared/'; 

到

import { EventStaffLogService } from '../shared/event-staff-log.service'; 
import { EventStaff } from '../shared/event-staff.model'; 

和它的工作。
