Мой код: у меня есть встроенный импортустройство в моем приложении module.ts и добавьте в провайдеры.

 App Module.ts
    import { Device } from '@ionic-native/device';

     providers: [
        Device,
        {provide: ErrorHandler, useClass: IonicErrorHandler}
     ]

, где я пытаюсь получить значения.следуя коду

import { Device } from '@ionic-native/device';
    constructor(
        public navCtrl: NavController,

Answer 1

Установка:

@ ionic-native / core @ ionic-native / device

введите описание ссылки здесь

ionic cordova plugin add cordova-plugin-device
npm install --save @ionic-native/device

Добавить этоПлагин для модуля вашего приложения

 // app.module.ts
import { Device } from '@ionic-native/device';

...

@NgModule({
  ...

  providers: [
    ...
    Device
    ...
  ]
  ...
})
export class AppModule { }

Использование

import { Device } from '@ionic-native/device';

constructor(private device: Device) { }

...

console.log('Device Model is: ' + this.device.model+
  '\n Device UUID is: ' + this.device.uuid+
  '\n Device serial is: ' + this.device.serial+
  '\n Device platform is: ' + this.device.platform+
  '\n Device version is: ' + this.device.version+
  '\n Device manufacturer is: ' + this.device.manufacturer);

Если не запустится, измените "import { Device } from '@ionic-native/device';" для "import { Device } from '@ionic-native/device/ngx';"

И "this.device.uuid" для "Расследовать""

Используйте эти команды для запуска в браузере

    ionic build

    ionic cordova platform add browser

    cordova run browser

И работает!в этих версиях

в браузере

в реальном устройстве

Answer 2

Не волнуйтесь.Похоже, вы запускаете ваше приложение по ionic serve --lab, а не на реальном устройстве или эмуляторе.

Вот почему вы получаете сообщение об ошибке.Ваш код в порядке.

Просто попробуйте запустить на эмуляторе или на реальном устройстве.

Если вы работаете на реальном устройстве, вы можете использовать средства отладки USB

и проверить по chrome://inspect/decvices
