deviceready在5000毫秒内没有发射 - 离子原生与信号

Question

我正在使用一个信号插件进行推送通知。

首先我安装了一个信号插件。

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

这是我的代码

this.platform.ready().then(() => {
      this.oneSignal.getIds().then((ids)=>{
          console.log("USER ID");
          console.log(ids.userId);
        }).catch((e)=>{
          console.log("error")
          console.log(e);
        })
    })

但是没有得到app id.why？

错误为plugin_not_installed。

我删除了这个插件再次添加。

但仍然得到同样的错误。并且还得到这种类型的错误。

Ionic Native: deviceready did not fire within 5000ms. This can happen when plugins are in an inconsistent state. Try removing plugins from plugins/ and reinstalling them.

请建议我，

感谢。
