我设法安装JDK 7，因为它是一个dmg文件，但是我在安装Java EE 7时遇到了问题...我已经在launchd.conf上注册了JAVA_HOME，但它仍然没有找到它...这里是错误：
sudo sh ./java_ee_sdk-7-unix.sh
Extracting the installer archive...

以及当我回应JAVA_HOME时会发生什么：
echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
有任何帮助吗？我是mac的新手
