GitHub Actions Issues with CB-CSV

By Evan Williamson | November 04, 2025

Folks have been encountering a build error when using the default “jekyll.yml” GitHub Action with fresh CollectionBuilder-CSV projects, with an error message something like:

The process '/opt/hostedtoolcache/Ruby/3.1.6/x64/bin/bundle' failed with exit code 5

There is some sort of dependency hell issue with the Sass requirements and the older Ruby version the default Action uses.

The best solution is to manually update the Ruby version specified in the “jekyll.yml”:

  • In your project look for the file “.github/workflows/jekyll.yml”.
  • Edit around line 40 where it says ruby-version: '3.1', updating it to ruby-version: '3.4'

That should fix the build! (Let us know if you encounter issues…)
