我正试图使用sencha cmd"sencha app build native"为Android构建一个sencha touch 2.4应用程序，但我遇到了一个无法解决的错误。
"您可能没有构建此项目所需的环境或操作系统"
我正在使用Win7，使用sencha touch 2.4和sencha cmd v5.1。我使用Android sdk管理器下载了Android sdk（API 19）。
这是命令输出：

提前感谢，如有任何帮助，我们将不胜感激。
如这里所建议的，Cordova/Ionic构建错误（有时）：don'；t具有所需的环境，要做的是将此"%SystemRoot%\system32；%SystemRoot%；%SystemRoot%\system32\Wbem；%SystemRoot%\system32\\WindowsPowerShell \v1.0"复制并粘贴到环境变量Path。
