Failed to find 'JAVA_HOME' environment variable in Mac
提问by ToniTJK
I'm new on Mac, so I installed Cordova (Node, Git, Grandle) but I can't execute it in my mobile phone, I mean I can't do "sudo Cordova run android" because it can't find "JAVA_HOME". When I installed I put this variable before... (It is a headache )
我是 Mac 新手，所以我安装了 Cordova（Node、Git、Grandle）但我无法在手机中执行它，我的意思是我无法执行“sudo Cordova run android”，因为它找不到“ JAVA_HOME”。当我安装时，我把这个变量放在了......（这是一个令人头疼的问题）
I tried to open the bash_profile but I didn't find it and if I open in terminal it always open a new file.
我试图打开 bash_profile 但我没有找到它，如果我在终端中打开它总是打开一个新文件。
If I do echo $JAVA_HOME, it is the result:
如果我做 echo $JAVA_HOME，结果是：
echo $JAVA_HOME
/usr/libexec/java_home
/usr/libexec/java_home
And this is my error:
这是我的错误：

You didn't install JAVA_HOMEcorrectly, therefore it fails.
您没有JAVA_HOME正确安装，因此它失败了。
You have to do it like following:
你必须这样做：
After installation you have to add installed java to system variable:
安装后，您必须将已安装的 java 添加到系统变量中：
Run in terminal for verification:
在终端中运行以进行验证：
java -version
java -version
The output should be something like:
输出应该是这样的：
java version "1.8.0_06-ea"
Java(TM) SE Runtime Environment (build 1.8.0_06-ea-b13)
Java HotSpot(TM) 64-Bit Server VM (build 23.2-b04, mixed mode)
After this check, you can import java to your IDE.
在此检查之后，您可以将 java 导入到您的 IDE 中。
