Easiest is to downgrade to Ruby 2.7 as that has been in use a lot time with Jekyll. Someone posted recently in the forums to say Ruby 3 works fine with Jekyll - he just had to delete all his system gems (i.e. remove Ruby 2 cleanly and then setup Ruby 3). ---

so I installed my ruby via brew following these steps - [Jekyll on macOS | Jekyll • Simple, blog-aware, static sites](https://jekyllrb.com/docs/installation/macos/) how would you downgrade to 2.7? ---

I wrote that Ruby 3 works well, but “delete all his system gems” it was not – just the ~/gems directory, and that rebuilt itself. ---

At the end of the Terminal window pointed properly at the subject folder … I get this after running … `Bundle install` ruby\_dep-1.5.0 requires ruby version ~\> 2.2, \>= 2.2.5, ;which is incompatible with the current version, ruby 3.0.1p64 Notice: Same warning w `Ruby 3.01` as w `Ruby 3.0.0` I’ve also tried purging the gem `ruby_dep`, but that doesn’t seem to work either, as follows: `gem uninstall ruby_dep-1.5.0` Returns, Gem ‘[ruby\_dep-1.5.0](https://rubygems.org/gems/ruby_dep/versions/1.5.0)’ is not installed. Yet there is still a warning call for “ruby\_dep-1.5.0” … That requires an ancient ruby version at the end of running of … `Bundle install` FYI: “[ruby\_dep-1.5.0](https://rubygems.org/gems/ruby_dep/versions/1.5.0)” has a last “worked on” version date of October 09, 2016 SOLUTION: 1.) Disable #gem ‘listen’, ‘3.1.5’ from Gemfile; 2.) Crank the version of `github-pages` down from `214` to `213` via the Gemfile; 3.) `Bundle update` Working … `Using github-pages 213` `Bundle updated!` ---
