在Ionic 3中運行release命令時，Angular AoT構建失敗

Question

我正在嘗試在Sony Z2智能手機上運行該應用程序。 我使用以下命令：

ionic build android --prod --release

我在控制台中收到如下錯誤：

打字稿錯誤C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.ts中的CirckelmovementPage類型是以下兩個模塊聲明的一部分：C：/ Users / fearcoder / Documents / natuurkundeformules / src / app中的AppModule /app.module.ts和CirckelmovementPageModule在C：/ Users / fearcoder /Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.module.ts中！

  Please consider moving CirckelmovementPage in 

C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.ts到將模塊導入C：/Users/fearcoder/Documents/natuurkundeformules/src/app/app/app.module.ts和CirckelmovementPageModule的更高模塊在C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.module.ts中。

  You can also create a new NgModule that exports and includes 

C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.ts中的CirckelmovementPage，然后將該NgModule導入C：/Users/fearcoder/Documents/natuurkundeformules/src/app/app.module.ts中的AppModule中。

  and CirckelmovementPageModule in 

C：/用戶/ fearcoder /文檔/natuurkundeformules/src/pages/circkelmovement/circkelmovement.module.ts。

這些是文件

我已經讀到該命令可以解決加載應用程序時的性能問題。 我不知道我在做什么錯。 有人可以指出我正確的方向嗎？

親切的問候

Answer 1

因此，當您使用延遲加載的頁面時，根本不需要在app.module.ts中導入或聲明這些頁面，因為它們將成為其文件夾中自己模塊的一部分。 因此，對於所有延遲加載的頁面都具有：

• 頁面的延遲加載頁面自己的命名模塊文件（您似乎在此特定頁面中擁有該文件）

• 在您的應用程序邏輯中，當您加載這樣的頁面時（例如，使用navCtrl），您需要將頁面名稱作為字符串而不是作為組件使用

因此，在代碼中取消注釋您懶加載的頁面：

還有一件事：請確保您對應用程序的命名約定非常謹慎。 我在這里看到：

@Component({
  selector: 'page-circkelmovement',
  templateUrl: 'circkelmovement.html',
})

您有不同的選擇器和模板url文件命名。 這可能會咬你；）以此為指導： https : //angular.io/guide/styleguide或遵循有關Ionic建議如何執行的示例，但最好在文件命名方面保持一致，例如：

• publish.page.html
• publish.page.module.ts
• publish.page.scss
• publish.page.ts
