LoadError for racc/parser.rb - prevents local Jekyll website build

Question

I am revisiting a static website I built a few years ago with Jekyll, and having trouble compiling the source locally to then send to my github pages website. I am not technically adept so please forgive any mistakes in the below.

The reason for the strange workflow is the need to use Jekyll-scholar and bibtex-ruby gems, so I basically have to build locally, then commit and deploy to github pages. I am seeing the issue below, which stops the jekyll build:

As you can see, I am using Ruby 3.3.0 - I'd appreciate any pointers on how to fix this - I see from other forums that there may have been a rights issue with the parser, but I don't know how to fix it, and basically even what I can do (what to comment out, in extremis) - the output format is very unintuitive. Thanks in advance!

I have tried downgrading the versions of relevant gems, and adding new gems suggested by forum posts, all with no luck.

I did not see any relevant posts on jekyllrb talk pages.

Answer 1

Add to your Gemfile gem 'racc' and run bundle install in my case it fixed this issue.
