问题
I use Catalina. I created the .bash_profile file and edited it.
I wrote export JAVA_HOME=$(/usr/libexec/java_home) in this file and typed source ~/.bash_profile, after that typed echo $JAVA_HOME and showed the path but when I reopen the terminal and type echo $JAVA_HOME, doesn't show the path again.
What is the problem?
回答1:
New user accounts in Catalina default to using zsh, not bash. You need to set your environment in ~/.zprofile, not ~/.bash_profile.
回答2:
~/.bash_profile is executed at the time of login. If you just log out and login again, it should be fine.
For interactive non-login shells .bash_rc is used.
