`cannot load such file -- rexml/document`

#rails #ruby

Author: vonhyou

Cause

rexml gem is a bundled gem since Ruby 3.0.0. So we must add rexml to Gemfile.

On Ruby 2.6 and 2.7, rexml gem is default gem. So default rexml is used if Gemfile does not include rexml. On these versions of ruby, we must add rexml to Gemfile only if we want to use specific rexml version.

Solution 

gem 'rexml', '~> 3.2', '>= 3.2.4'

Add the code above to Gemfile
