RBS gen doesn't work with Truffleruby #2691

Closed mrwormhole closed 2 years ago

mrwormhole commented 2 years ago

Ruby Version truffleruby 22.3.0-dev-3dfcaa03, like ruby 3.0.3, GraalVM CE Native [x86_64-linux]

RBS gem version 2.6.0

Error message I am getting when I run the command

class Dog
  def bark
    "woof,woof"
  end
end
rbs prototype rb dog.rb
Not supported on this interpreter (truffleruby).

Notes It works on other ruby versions

As it says, rbs prototype doesn't support anything but CRuby, because it depends on RubyVM, an unstable experimental CRuby-specific API: https://github.com/ruby/rbs/issues/348 The rest of rbs should work.
