Question

一段时间以来，我一直在尝试编写代码以使Ionic的App构建不再那么久。像大多数用户一样，我使用

https://ionicframework.com/docs/native/background-geolocation编写代码。

此插件不起作用，我正在寻找不使用该插件的最佳方式。

我已经完成的工作使用了ionic 4本机文档中的代码完成，于2018年12月奏效。一段时间后，我今天打开了我的应用程序。应用程序崩溃了，我重新编写了代码。尝试了不同版本的插件，但无济于事，它们无法正常工作。


setBackgroundTracking(){
    this.backgroundGeolocation.configure(config)
          .then(() => {

            this.backgroundGeolocation.on('location').subscribe((location: BackgroundGeolocationResponse) => {
              console.log(location);

              // IMPORTANT:  You must execute the finish method here to inform the native plugin that you're finished,
              // and the background-task may be completed.  You must do this regardless if your operations are successful or not.
              // IF YOU DON'T, ios will CRASH YOUR APP for spending too much time in the background.
              this.backgroundGeolocation.finish(); // FOR IOS ONLY
            });

          });


The above code is an exact copy paste from the documentation. and the code is buggy.

Property 'subscribe' does not exist on type 'Promise<any>'.ts(2339)

If you guys can fix the code or tell me another way to do it, please let me know. I have just been brainstorming would appreciate input/

似乎您无法从文档中复制/粘贴：

this.backgroundGeolocation.configure(config)
  .then(() => {

    this.backgroundGeolocation.on('location').subscribe((location: BackgroundGeolocationResponse) => {
      console.log(location);
