默认的Gradle安装是Android Studio SDK的一部分，因此，如果您移动Android Studio文件的位置或在您的环境中定义了错误的PATH，则找不到sdk的位置是这样的.如果您的路径是其他android studio安装版本，则可能其中没有特定版本的gradle.

The default gradle install is part of Android Studio sdk so if you moved your Android Studio files location or have the wrong PATH defined in your environment it won't find the sdk location like this. If your path is to a different android studio installation version it might not have that particular version of gradle in it.
