Hi, do you have the paginator gem installed? If not, then you’ll need  
to  
do the following:

using RVM:

gem install paginator

Otherwise, you may need to do the following:

sudo gem install paginator

Next, did you add 'config.gem ‘paginator’ to your environment.rb file?  
If  
not, you  
should do so now. Also, I would recommend reviewing the docs if you  
haven’t  
done so here:

[http://paginator.rubyforge.org/](http://paginator.rubyforge.org/)

[http://paginator.rubyforge.org/](http://paginator.rubyforge.org/)Lastly, I would recommend using  
‘will\_paginate’ gem instead of the ‘paginator’ gem for pagination.

Good luck,
