Question

我目前正在从事离子项目。但是，当我尝试为Android生成发行版时，会出现以下错误：

 Android Studio project detected
(node:13116) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'variables' of undefined
    at C:\Users\Digitalis 2\AppData\Roaming\npm\node_modules\cordova\node_modules\cordova-lib\src\cordova\restore-util.js:322:57

我在右边的文件夹中执行了命令：ionic cordova build --release android，我的所有软件包都是最新的。

如果有人知道我为什么会收到此错误（我不理解）以及如何解决它，我将非常感激！

我找到了答案，cordova-barcode-scanner插件有问题。版本太旧，我不得不切换到phonegap-plugin-barcodescanner，一切正常！
