Rufo can be installed in Ruby 3.1.2, but failed in Ruby 3.3.6
Error message:

ERROR:  While executing gem ... (NoMethodError)

I cannot reproduce it. What are the steps to reproduce the problem?

That's weird. The ruby was installed by rbenv on MACOS 15.0

ruby -v
ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24]

What is the jaro_winkler gem and is it related to rufo?
Does this happen with other gems than rufo?
Does it happen with other versions of rufo?
