Error on bootstrap gem

Question

I've been getting the following error after trying to install the bootstrap gem. I've followed the advice found elsewhere but it doesn't seem to be working. I definitely always remember to restart my server after bundle install but I'm still having trouble.

Showing /home/ubuntu/workspace/sample_app/app/views/static_pages/home.html.erb where line #13 raised:

File to import not found or unreadable: bootstrap-sprockets.

Gemfile:

Thanks for any help!

Add the to the Gemfile the gem sass-rails :

gem 'bootstrap-sass', '~> 3.3.6'
gem 'sass-rails', '>= 3.2'
