rexml Is A Bundled Gem As Of Ruby 3.0.0

Are you seeing an error loading certain rexml files?

LoadError: cannot load such file -- rexml/document

It may be that rexml no longer ships as part of the Ruby version you are using. If you are working with Ruby 3.0.0 or later, the rexml gem needs to be explicitly installed as it is now a bundled gem.

Either add it to your Gemfile:

gem 'rexml'

or install it manually with:

$ gem install rexml
