提问by Drew
I am trying to create an ionic application, and when I go to link pages together in the ionic creator, I am getting an error on the .ts file as follows:
我正在尝试创建一个 ionic 应用程序，当我在 ionic creator 中将页面链接在一起时，我在 .ts 文件中收到如下错误：
typescript: src/pages/home/home.ts, line: 4
Individual declarations in merged declaration 'HomePage' must be all exported or all local.
L3: import { NotificationsPage } from '../notifications/notifications';
L4: import { HomePage } from '../home/home';
L5: import { MyPatientsPage } from '../my-patients/my-patients';
Below is the code from my .ts file:
下面是我的 .ts 文件中的代码：
import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { NotificationsPage } from '../notifications/notifications';
import { HomePage } from '../home/home';
import { MyPatientsPage } from '../my-patients/my-patients';
import { AllPatientsPage } from '../all-patients/all-patients';
import { LoginPage } from '../login/login';
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
constructor(public navCtrl: NavController) {
}
goToNotifications(params){
if (!params) params = {};
this.navCtrl.push(NotificationsPage);
}goToHome(params){
if (!params) params = {};
this.navCtrl.push(HomePage);
}goToMyPatients(params){
if (!params) params = {};
this.navCtrl.push(MyPatientsPage);
}goToAllPatients(params){
if (!params) params = {};
this.navCtrl.push(AllPatientsPage);
}goToLogin(params){
if (!params) params = {};
this.navCtrl.push(LoginPage);
}
}

You must not importthe HomePageinside the home.tsfile.i.e.Line 4
你不能import在HomePage里面的home.ts文件。IELine 4
Need to remove below import from the home.tsfile
需要从home.ts文件中删除以下导入
import { HomePage } from '../home/home';
