在Linux上运行:whereis gradle。

对我来说是/usr/lib/gradle/1.10。

如果你在windows机器上，转到C:\Program Files\Android\Android Studio\gradle\目录，点击gradle文件夹并应用它

我也遇到了同样的问题。我选择位置C:\Program Files (x86)\Android\ android-studio\plugins\gradle作为gradle Home

在Ubuntu 14.04 $ sudo后apt-get安装gradle 我有

$ whereis gradle
gradle: /usr/bin/gradle /usr/bin/X11/gradle /usr/share/gradle /usr/share/man/man1/gradle.1.gz

Gradle的路径是/usr/share/gradle

Mac OSX / Linux

Step 1: Open terminal :)
Step 2: Open .bash_profile in vim to edit: 
        > vi ~/.bash_profile 
Step 3: Add line: 
        > export GRADLE_HOME=/usr/local/opt/gradle 
        (for me it was this location, it can be different for u)
Step 4: Add line: 
        > export PATH="$PATH:$GRADLE_HOME/bin" 
        (to export bin directory of gradle)
Step 5: Verify by reopening the terminal or new tab, and check by echoing: 
        > echo $GRADLE_HOME

在Windows上
