But When my JAVA_HOME is called by Ionic I have :


I don't know why my JAVA_HOME is not same.

I try to launch . .bash_profile but don't work

  • you should try 'source .bash_profile' The file is probably not executable. Or open a new terminal window. – Natsfan Dec 14 '18 at 15:29

    @jmh the dot is the same as source – Allan Dec 14 '18 at 15:46
  • Can you post the contents of your ~/.bash_profile please. Also, start a new session and post the output of echo $JAVA_HOME – Allan Dec 14 '18 at 15:47
  • i put an echo statement in all my profiles, so that I know which ones have run. – historystamp Dec 16 '18 at 5:34

Per memory in the .bash_profile when I used to dabble in Java you need to add export and ". In the Terminal run the command:

 nano .bash_profile

Then add:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_191.jdk/Contents/Home"

Then do the reboot of: . .bash_profile after you've saved the bash_profile


Bash uses its various rc files differently depending on how it's invoked. Read the INVOCATION section of the bash man page for the specifics but briefly for a login shell it will read bash_profile (along with other things), and for a non-login shell, it will read bashrc (along with other things). Most people will source bashrc from their bash_profile and do everything else in bashrc.

You don't show it, but presumably you're not export-ing JAVA_HOME. You should. You want to make sure that goes to the parent shell.
