Failed to find 'JAVA_HOME' environment variable in Mac

Question

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 🤕)

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.

If I do echo $JAVA_HOME, it is the result:

echo $JAVA_HOME

/usr/libexec/java_home

And this is my error:

sudo cordova run android --target=ZY223T38PM

Answer 1

You didn't install JAVA_HOME correctly, therefore it fails.

You have to do it like following:

• 10 JDK 8 Installation for OS X

After installation you have to add installed java to system variable:

• How to Set $JAVA_HOME environment variable on Mac OS X
• What should I set JAVA_HOME to on OSX

Run in terminal for verification:

java -version

The output should be something like:

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.
