Title: Check for Sprockets before using register_processor

In my case, I'm running Rails without the sprockets railtie:

%w{ active_record action_controller }.each do |railtie|
begin
require "#{railtie}/railtie"
rescue LoadError
end
end

This fix helps check for Sprockets before using the register_processor method in js.rb.
