cordova - 无法读取未定义的属性 'find' (UnhandledPromiseRejectionWarning)

Question

我正在使用 Angular/Firebase 在 Ionic 中构建一个应用程序。

我想在我的 Android 设备上测试该应用程序，该设备以前运行良好。但是，最近我无法运行它，因为出现错误。

$ ionic cordova run android --device --prod

这会导致错误:

我不确定为什么会发生这种情况。我尝试删除我的 node_modules 文件夹，然后执行 npm install，但这并没有解决问题。我想这可能是安卓的问题？因为我仍然能够在 iOS 上构建...

有什么想法吗？谢谢!!

Answer 1

设法(暂时？)通过删除 android 并重新安装来解决此问题...

cordova platform remove android
cordova platform add android

希望这可以帮助将来的人。
