[ERROR] An error occurred while running subprocess cordova.

    cordova.cmd build android exited with exit code 1.

    Re-running this command with the --verbose flag may provide more information.

Answer 1

如錯誤日志中的以下兩行所示，您尚未正確安裝Android SDK：

ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=C:\Users\66907\AppData\Local\Android\Sdk (DEPRECATED)

如果您先前已安裝SDK，則將ANDROID_SDK_ROOT與安裝路徑添加到您的環境。 如果尚未安裝SDK，那么最簡單的方法是安裝Android Studio並從那里管理安裝。 Android studio還將處理所有環境變量。
