您好我正在尝试使用命令ionic cordova build android --prod

构建用于生产的Android应用程序

问题是在运行此代码后，它给了我以下打字稿错误。

    typescript error
    Type ContactPage in C:/Users/Akshay S. Shrivastav/Desktop/vidyotan_2k18/src/pages/contact/contact.ts is part
    of the declarations of 2 modules: AppModule in C:/Users/Akshay S.
    Shrivastav/Desktop/vidyotan_2k18/src/app/app.module.ts and ContactPageModule in C:/Users/Akshay S.
    Shrivastav/Desktop/vidyotan_2k18/src/pages/contact/contact.module.ts! Please consider moving ContactPage in
    C:/Users/Akshay S. Shrivastav/Desktop/vidyotan_2k18/src/pages/contact/contact.ts to a higher module that
    imports AppModule in C:/Users/Akshay S. Shrivastav/Desktop/vidyotan_2k18/src/app/app.module.ts and
    ContactPageModule in C:/Users/Akshay S.
    Shrivastav/Desktop/vidyotan_2k18/src/pages/contact/contact.module.ts. You can also create a new NgModule
    that exports and includes ContactPage in C:/Users/Akshay S.
    Shrivastav/Desktop/vidyotan_2k18/src/pages/contact/contact.ts then import that NgModule in AppModule in
    C:/Users/Akshay S. Shrivastav/Desktop/vidyotan_2k18/src/app/app.module.ts and ContactPageModule in
    C:/Users/Akshay S. Shrivastav/Desktop/vidyotan_2k18/src/pages/contact/contact.module.ts.

这是我的app.component.ts 

import { Component, ViewChild } from '@angular/core';
import { Nav, Platform } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

import { HomePage } from '../pages/home/home';
import { EventsPage } from '../pages/events/events';
import { WorkshopsPage } from '../pages/workshops/workshops';
import { TeamPage } from '../pages/team/team';
import { ContactPage } from '../pages/contact/contact';
import { DeveloperPage } from '../pages/developer/developer';
import { WildcardPage } from '../pages/wildcard/wildcard';
// import { DetailsPage } from '../pages/details/details';

@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  @ViewChild(Nav) nav: Nav;

rootPage: any = HomePage;

pages: Array<{title: string, component: any}>;

constructor(public platform: Platform, public statusBar: StatusBar, public splashScreen: SplashScreen) {
  this.initializeApp();

  //menu navigators
  this.pages = [
    { title: 'Home', component: HomePage },
    { title: 'Events', component: EventsPage },
    { title: 'Wildcard Entries', component: WildcardPage },
    { title: 'Workshops', component: WorkshopsPage },
    { title: 'Vidyotan Team', component: TeamPage },
    { title: 'Contact', component: ContactPage },
    { title: 'App Developer', component: DeveloperPage },
  ];

}

initializeApp() {
  this.platform.ready().then(() => {
    // Okay, so the platform is ready and our plugins are available.
    // Here you can do any higher level native things you might need.
    // this.statusBar.styleDefault();
    this.statusBar.backgroundColorByHexString("#337ab7");
    this.splashScreen.hide();
  });
}

openPage(page) {
  // Reset the content nav to have just this page
  // we wouldn't want the back button to show in this scenario
  this.nav.setRoot(page.component);
}
}

这是我的app.module.ts 

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

import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { EventsPage } from '../pages/events/events';
import { WorkshopsPage } from '../pages/workshops/workshops';
import { TeamPage } from '../pages/team/team';
import { ContactPage } from '../pages/contact/contact';
import { DeveloperPage } from '../pages/developer/developer';
import { DetailsPage } from '../pages/details/details';
import { WildcardPage } from '../pages/wildcard/wildcard';

import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

@NgModule({
  declarations: [
    MyApp,
    HomePage,
    EventsPage,
    WorkshopsPage,
    TeamPage,
    ContactPage,
    DeveloperPage,
    DetailsPage,
    WildcardPage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage,
    EventsPage,
    WorkshopsPage,
    TeamPage,
    ContactPage,
    DeveloperPage,
    DetailsPage,
    WildcardPage
  ],
  providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

这是我的contact.ts 

import { Component } from '@angular/core';
    import { IonicPage, NavController, NavParams } from 'ionic-angular';

    // import { Contact1Page } from '../contact/contact';

    @IonicPage()
    @Component({
      selector: 'page-contact',
      templateUrl: 'contact.html',
    })
    export class ContactPage {

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

      ionViewDidLoad() {
        console.log('ionViewDidLoad ContactPage');
      }

    }

这是我的contact.module.ts 

import { NgModule } from '@angular/core';
    import { IonicPageModule } from 'ionic-angular';
    import { ContactPage } from './contact';

    @NgModule({
      declarations: [
        ContactPage,
      ],
      imports: [
        IonicPageModule.forChild(ContactPage),
      ],
    })
    export class ContactPageModule {}

可能是什么问题我无法得到它。 UI已根据我做了所有事情我也搜索了各种论坛，但在为生产环境构建应用程序时仍然出现同样的错误。

请帮助，提前致谢。

从“申报”中删除“ContactsPage”，并在“AppModule.ts”中输入“components”，因为它已经在“contact.module.ts”中导入了

答案 1 :(得分：1)

我已经多次面对这个问题，因为离子说特定页面是两个声明的一部分，一个是我们的主要应用程序组件声明，第二个是单个组件模块。 所以基本上从单个component.module.ts文件中删除它对我来说很有用，所以尝试从contact.module.ts文件中删除页面声明

@NgModule({
  declarations : [
                     //keep this empty 
  ],
  imports : [
   .... 
  ]

您不需要在<a href="#" onClick = "{{ pyperclip_Test }}; return false">Test</a> <div>Data that I want to copy</div> 文件中声明import boto import sys, os from boto.s3.key import Key from boto.exception import S3ResponseError DOWNLOAD_LOCATION_PATH ="" BUCKET_NAME = "" AWS_ACCESS_KEY_ID= "" AWS_ACCESS_SECRET_KEY = "" conn = boto.connect_s3(AWS_ACCESS_KEY_ID, AWS_ACCESS_SECRET_KEY) bucket = conn.get_bucket(BUCKET_NAME) #goto through the list of files bucket_list = bucket.list() for l in bucket_list: key_string = str(l.key) s3_path = DOWNLOAD_LOCATION_PATH + key_string try: print ("Current File is ", s3_path) l.get_contents_to_filename(s3_path) except (OSError, S3ResponseError) as e: pass # check if the file has been downloaded locally if not os.path.exists(s3_path): try: os.makedirs(s3_path) except OSError as exc: # let guard againts race conditions import errno if exc.errno != errno.EEXIST: raise ，因为它已在ContactPage文件中声明。因此，您必须从app.module.ts文件中的声明和 entryComponents 中删除contact.module.ts。
