属性 'subscribe' 在类型 'Promise<any>' 上不存在 @ionic-native/background-geolocation 插件中的错误

Question

我正在尝试为我的应用程序实施后台地理定位捕获，但出现错误属性 'subscribe' 在类型 'Promise' 上不存在。这是我的代码。 app.module.ts

import { BackgroundGeolocation } from '@ionic-native/background-geolocation/ngx';

 providers: [
    BackgroundGeolocation,
    ],

liveLocation.service.ts

import { Injectable } from '@angular/core';
import { BackgroundGeolocation, BackgroundGeolocationConfig, BackgroundGeolocationResponse }
 from '@ionic-native/background-geolocation/ngx';

const config: BackgroundGeolocationConfig = {
  desiredAccuracy: 10,
  stationaryRadius: 20,
  distanceFilter: 30,
  debug: true, //  enable this hear sounds for background-geolocation life-cycle.
  stopOnTerminate: false, // enable this to clear background location settings when the app terminates
};

@Injectable({
  providedIn: 'root'
})


export class LiveLocationService {

  constructor(private backgroundGeolocation: BackgroundGeolocation) { }

  LiveLocationCapturing(){

    this.backgroundGeolocation.configure(config)
  .subscribe((location: BackgroundGeolocationResponse) => {

    console.log(location);


  });

  }
}

错误：

  ERROR in src/app/service/liveLocation/live-location.service.ts(25,4): error TS2339: Property 'subscribe' does not exist on type 'Promise<any>'.

有了 Promise，就是 .then()。使用 Observable，你是对的，它是 .subscribe()
