ionic serve - Runtime Error : Push plugin not found (IONIC 2)

Question

我使用以下代码在 ionic 2 应用程序中使用推送通知。

import { Push, PushToken } from '@ionic/cloud-angular';
   @Component({...})
   export MyPage {     
    constructor(public platform: Platform, public menu: MenuController, public push: Push){
     this.initializeApp();
    }
    initializeApp() {
      this.platform.ready().then(() => {
       if (this.push) {
        this.push.register().then((t: PushToken) => {
          return this.push.saveToken(t);
        }).then((t: PushToken) => {
          console.log('Token saved:', t.token);
          window.localStorage.setItem("deviceToken", t.token);
        });

        this.push.rx.notification()
          .subscribe((msg) => {
            alert(msg.title + ': ' + msg.text);
            console.log('notification msg', msg);
          });
        }
      }
    }
}

当我运行在设备上时，它工作正常。但我做离子服务它给出了以下错误，因为在构造函数

中注入了Push

任何帮助都适用

Answer 1

您应该在执行cordova 操作之前检查cordova 对象是否存在。

服务中不存在，因为浏览器不是移动设备

initializeApp() {
      this.platform.ready().then(() => {
       if(!(<any>window).cordova) return;
       ...the native code you want to execute...
      });
    }

Answer 2

检查 package.json 文件中 dependencies.

中是否有行 "@ionic/cloud-angular":"^ 0.9.0"

如果是，将其切换为^0.9.1，将文件和运行 npm install保存在项目根文件夹中。这应该将 @ionic/cloud-angular 更新为 0.9.1 并将其 @ionic/cloud 依赖项更新为 0.15.1.

然后运行 ionic serve 它应该可以工作。
