Warning: node.js detection failed, sbt will use the Rhino based Trireme JavaScript engine

Question

I\'m new to Play framework. Please explain the meaning of the below warning.

Warning: node.js detection failed, sbt will use the Rhino based Trireme J

Answer 1

You need to install Node.js and then tell the sbt/java engine to use it.

  brew install node

Edit .bash_profile and add:

   export SBT_OPTS="${SBT_OPTS} -Dsbt.jse.engineType=Node -Dsbt.jse.command=$(which node)"

This eliminated the warning for me on OSX
