Question about to try TruffleRuby about truffleruby HOT 4 CLOSED

The master branch of TruffleRuby isn't always compatible with GraalVM, as APIs change. We recommend people who want to build TruffleRuby from scratch build graalVM from source.

Does that allow you to do what you want? Or did you have some complex requirement where you really want to use GraalVM?

Want to try in real application like rails, I think You do super job! Thank you.
So for build graalVM from source.

What JAVA required? Can I use JDK9 from here or what version do I need for macOS?

from truffleruby.

Ruby is also part of the GraalVM itself. Using TruffleRuby from a repo is recommended only when you need newer version than the version of TruffleRuby included in GraalVM or for contributing to TruffleRuby. Latest version of TruffleRuby should be out in GraaVM 0.21 in few days. Ruby from GraalVM 0.21 only has to be added to a Ruby manager before use. No compilation needed.

Correct version might be already included in GraalVM depending on which version you've downloaded. Otherwise the link you've posted is ok or the Java8 from Oracle OTN will work too.

Yes, for your use case you should use the version of Ruby included with GraalVM.
