無法構建Ionic 2項目

我將ionic 2項目遷移到最新版本（即3.0.0）。一切都很完美，直到我今天在項目中生成了一個新頁面（DiscountOption）。它生成4個文件而不是3個（* .module.ts是新的）。無法構建Ionic 2項目

這裏是我的代碼：

量販option.module.ts

import { NgModule } from '@angular/core'; 
import { IonicPageModule } from 'ionic-angular'; 
import { DiscountOption } from './discount-option'; 

@NgModule({ 
    declarations: [ 
    DiscountOption, 
    ], 
    imports: [ 
    IonicPageModule.forChild(DiscountOption), 
    ], 
    exports: [ 
    DiscountOption 
    ] 
}) 
export class DiscountOptionModule { }

app.module.ts

... 
import { DiscountOption } from '../pages/orders/biller/discount-option/discount-option'; 

@NgModule({ 
    declarations: [ 
    ... 
    DiscountOption 
    ], 
    imports: [ 
    BrowserModule, 
    HttpModule, 
    IonicModule.forRoot(MyApp), 
    IonicStorageModule.forRoot() 
    ], 
    bootstrap: [IonicApp], 
    entryComponents: [ 
    ... 
    DiscountOption 
    ], 
    providers: [ 
    ... 
    ] 
}) 
export class AppModule { }

（...代碼縮短簡潔）

當我試圖建立應用程序使用ionic build android --prod

我得到這個錯誤，

我知道這個錯誤是由於在申報兩次app.module模塊和新生成的模塊文件。我不知道如何使它工作。任何意見將是有益的。謝謝。

檢查google docs regarding ionic v3。

從app.module.ts刪除對DiscountOption頁面的任何引用。

@NgModule({ 
    declarations: [ 
    ... 
    ], 
    imports: [ 
    BrowserModule, 
    HttpModule, 
    IonicModule.forRoot(MyApp), 
    IonicStorageModule.forRoot() 
    ], 
    bootstrap: [IonicApp], 
    entryComponents: [ 
    ... 
    ], 
    providers: [ 
    ... 
    ] 
}) 
export class AppModule { }

您的網頁會被引用，並在page.module.ts

如果要導入的頁面其他地方將其刪除..使用等效字符串類的name.Also添加@IonicPage()聲明在DiscountOption

@IonicPage() 
@Component({ 
    templateUrl: 'discount-option.html' 
}) 
export class DiscountOption {}

參考：IonicPage

感謝您的回覆，我刪除了引用，並且構建了該項目。但是當我在設備上運行它時，頁面不顯示。當我在瀏覽器中使用它時，控制檯顯示錯誤'沒有找到DiscountOption的組件工廠。你把它添加到@ NgModule.entryComponents？'。我需要在app.module.ts中引用它，這與答案直接矛盾！ –

你在app.component.ts中導入了頁面嗎？ –

可以肯定的是，它是app.component.ts還是app.module.ts？ –

如果你不ü唱Ionic 3懶惰加載功能，只需刪除你的網頁的yourPage.module.ts。它是一個可選之一。

只是好奇你對懶惰加載功能有什麼看法？ –

請參閱此文檔：https：//docs.google.com/document/d/1vGokwMXPQItZmTHZQbTO4qwj_SQymFhRS_nJmiH0K3w/edit#heading=h.yw70uq35xyz8 @suraj – Sampath

我已閱讀它..我在我的答案中引用它:) ..不確定關於將每個頁面/組件轉換爲其自己的模塊雖然.. –
