Question

我重新打开了旧的Ionic项目，当我尝试构建它时，出现“无法读取未定义的属性'length'的错误”错误。

注意：我最近更新了Android Studio

我尝试卸载并安装节点和离子

错误

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=H:\sdk (DEPRECATED)
Cannot read property 'length' of undefined
[ERROR] An error occurred while running subprocess cordova.

        cordova.cmd build android exited with exit code 1.

离子信息：
