在Ionic 3

Question

我正在尝试在我的Sony Z2智能手机上运行该应用程序。我使用以下命令：

ionic build android --prod --release

我的控制台出现错误，如下所示：

  

打字稿错误               在C中键入CirckelmovementPage：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.ts             是2个模块的声明的一部分：AppModule in   C：/Users/fearcoder/Documents/natuurkundeformules/src/app/app.module.ts   和CirckelmovementPageModule在C：/ Users / fearcoder中               /Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.module.ts！

      Please consider moving CirckelmovementPage in

     

C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.ts             到更高的模块，导入AppModule   C：/Users/fearcoder/Documents/natuurkundeformules/src/app/app.module.ts             和CirckelmovementPageModule in   C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.module.ts

      You can also create a new NgModule that exports and includes

     

CirckelmovementPage in   C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.ts   然后导入那个NgModule               在AppModule中的C：/Users/fearcoder/Documents/natuurkundeformules/src/app/app.module.ts

      and CirckelmovementPageModule in

     

C：/Users/fearcoder/Documents/natuurkundeformules/src/pages/circkelmovement/circkelmovement.module.ts

这些是文件

circkelmovement.ts

import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { AdMobFree, AdMobFreeBannerConfig } from '@ionic-native/admob-free';

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

export class CirckelmovementPage {

  ray:any;
  circulationtime:any;
  result:any;

  constructor(public navCtrl: NavController, public navParams: NavParams, private admob: AdMobFree) {
  } 

  ionViewDidLoad(){
    const bannerConfig: AdMobFreeBannerConfig = {
      isTesting: true,
      autoShow: true
    };
    this.admob.banner.config(bannerConfig);

    this.admob.banner.prepare()
      .then(() => {
        this.admob.banner.show()
      })
      .catch(e => console.log(e));
  }

  calculateWebSpeed(ray, circulationtime){      
    return this.result = "Baansnelheid: " + (2 * Math.PI * ray / circulationtime) + " m/s";

我已经读过这个命令可以解决加载应用时的性能问题。我不知道我做错了什么。有人能指出我正确的方向吗？

亲切的问候

Answer 1

因此，当您使用延迟加载的页面时，您根本不需要在此app.module.ts中导入或声明它们，因为它们将成为其文件夹中自己模块的一部分。所以对于所有延迟加载的页面都有：

• 延迟加载页面在页面中拥有自己的命名模块文件（您似乎拥有该特定页面的文件）

加载此类页面时，在您的应用程序逻辑中

• （例如使用navCtrl），您需要将页面名称用作字符串而不是作为组件

因此，在您的代码中，取消注释那些延迟加载的页面：

import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';

还有一件事：确保您对应用程序的命名约定非常小心。我在这看到：

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

您有不同的选择器和模板url文件命名。这可以咬你;） 使用此作为指导：https://angular.io/guide/styleguide或遵循Ionic如何建议的示例，但理想情况下在文件命名方面具有一致性，例如：

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