Incompatible with the current version, ruby 3.0

1

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

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.

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’ 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” 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!
