I hit a similar error and downgrading from Ruby 3.3.0 to Ruby 3.2.2 fixed the problem for me. I’m running Jekyll 4.3.2. If you can, upgrade to [Jekyll 4.3.3](https://github.com/jekyll/jekyll/releases/tag/v4.3.3) and try again with Ruby 3.3.0. The release notes suggest your problem should be fixed there. ---

I had this same issue and upgrading to Jekyll 4.3.3 fixed it. Thanks! ---

I also had this issue, and after banging my head against a wall for _\>1 hour_, I realized that downgrading to Ruby 3.2.3 fixed it. But weirdly I had some issue when re-installing ruby with `brew`, and I ran in some strange errors in terminal when running `bundle`. I decided to use `chruby` instead to manage ruby version, going ahead. I published a [post on medium](https://medium.com/@ritviknag/ruby-versioning-trouble-with-jekyll-github-pages-fd2748bf4e1d) that go into more detail, if anyone’s curious. This is what ended up working for me. ---

Crap yeah, good catch. I meant 3.2.3. Sometimes the numbers are very easy to confuse. _Edit_: fixed it, thanks. ---

Worked for me with Jekyll 4.3.3 and Ruby 3.3.3. 👍
