Question

我无法弄清楚为什么我不能再在使用Cordova的同一台计算机上构建Android应用程序，而这些计算机是在我更新Cordova和NodeJS之后构建上个月运行的相同应用程序的。目前，我必须利用超级用户权限才能获得Cordova启动模拟器，但它无法在模拟器上安装应用程序，并随后因以下错误而崩溃。首先以

为根

sudo -E su

然后cordova命令将启动没有sudo的模拟器

cordova emulate android

如果我尝试使用cordova运行android，我就无法在连接的设备上启动。以下是删除root然后运行emulate命令后的输出。

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

我以前从未必须使用Cordova启动Android模拟器，为什么目前就是这种情况，为什么应用程序没有在模拟器上安装？

为什么我需要根目录来编译那些无效的Cordova应用程序？
