I am trying to use a particular gem that hasn’t been updated since the inception of Rails 3. It makes a reference to RAILS_ROOT when the gem is initialized, which gives me this:
can't convert #<Class:0x1018695c8> into String (TypeError)
From my understanding, this is because Rails 3 doesn’t set Rails.root at this stage of the initialization process. Is there a way I can patch this gem, or add something somewhere to fix this issue?
from what I could find from a quick search, it looks like the way to go is to create a Rails::Railtie for it
