Where was scala_home homebrew installed on OSX?

Question

I can't get scalac working despite scala successfully opening scala> in the terminal. I suspect this is something to do with setting scala_home in my .bash_profile, on my mac. What is the correct value for SCALA_HOME, or how do I find that correct value? (it was homebrewed)

And is the method to scale-compile the following: to cd into the lower src folder and scalac IntroducingScala.HelloWorld.scala?

Answer 1

Homebrew usually tells you where it installs if you do brew info <name>. It's usually points at /usr/local/opt/<name>, which will be a symlink to the current version you're running.

When I run brew info scala it also comes with a helpful caveat:

To use with IntelliJ, set the Scala home to:
/usr/local/opt/scala/idea
