Linux下安装Android Studio出错，求大神解答！

JDK都配置好了，运行

  zoegreen@zoegreen-Lenovo-IdeaPad-Y470:/opt/android-studio/bin$ java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Server VM (build 24.51-b03, mixed mode)

但在最后一步执行./studio.sh时不能打开studio，出现以下错误：

 zoegreen@zoegreen-Lenovo-IdeaPad-Y470:/opt/android-studio/bin$ sudo ./studio.sh
[sudo] password for zoegreen:
