Getting "cat: /release: No such file or directory" when running scala

I tried to install Scala 2.12.1 on my Mac (El Capitan) via Homebrew and also by downloading the binaries from https://www.scala-lang.org/download/.

In both cases, whenever I run scala (or scalac, scaladoc, etc) I get this printed to screen:

cat: /release: No such file or directory

The action is successful however. E.g. scala myscript.scala works just fine, but that error message gets printed first.

Does anyone have an idea of why that's happening?

Solution

  • Opening up bin/scala, there's a line:

    java_release="$(cat $JAVA_HOME/release | grep JAVA_VERSION)"

    My $JAVA_HOME wasn't set. All fixed now.
