Incompatible with the current version, ruby 3.0

I’m running into this error ruby_dep-1.5.0 requires ruby version >= 2.2.5, ~> 2.2, which is incompatible
with the current version, ruby 3.0.0p0 when trying to bundle exec jekyll serve any thoughts?

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 how would you downgrade to 2.7?

brew install ruby@2.7

My guide Install Ruby and Bundler · GitHub

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

Oh good thanks for jumping in.
