Unable to load gems in cloud 9

Question

I cannot load many ruby gems in Cloud 9's ruby on rails.

For example I run

$ gem install signer

and get:

Successfully installed signer-1.4.2
1 gem installed

but then when I try to call it with:

require "signer"

I get the following error upon running:

cannot load such file -- signer

I am getting desperate, any help would be immensely appreciated!

Adding the following line to the Gemfile within your Rails folder:

gem 'signer', '~> 1.4.2'

and then running bundle install should remove the error.
