无法读取未定义的 属性 'find' (UnhandledPromiseRejectionWarning)
Cannot read property 'find' of undefined (UnhandledPromiseRejectionWarning)
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，该设备之前运行良好。但是，最近我无法 运行 它，因为出现错误。
$ ionic cordova run android --device --prod
然后导致错误：

我不确定为什么会这样。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。我认为这可能是 android 问题？因为我仍然能够在 iOS...
有什么想法吗？谢谢！！
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
希望这对以后的人有所帮助。
您可以编辑文件
cordova\node_modules\cordova-common\src\util\xml-helpers.js:207:26
并添加
if(doc!==null) //add this line
parent = doc.find(selector);
它还有助于编译和安装 android 应用程序
