I'm trying to work through a few issues with gems and attempting to use Ruby 2.7.5 and/or 3.0.3 via nixpkgs, and there seem to be some weird issues around installing gems correctly and ascertaining the ruby version, and this seems relevant.
Version mapping in Bundix only includes Ruby versions from 1.8 to 2.6:
On the other hand, the latest version of bundler in nixpkgs is now based on bundler 2.3.6 (which lists Ruby versions up to 3.0) here but in the mean time Ruby 3.1.0 and 3.1.1 have now been released.

This seems to be a hard-coded duplication of the list available versions from bundler
1.x.x(which is now very outdated):https://github.com/rubygems/rubygems/blob/d7089abb6a3c922bfe74199c103e745bb11bd46f/lib/bundler/current_ruby.rb#L12-L22
