You will need to have guard to contine, so install it now!.

Install the gem with:

gem install guard-sass

Add it to your Gemfile:

gem 'guard-sass'

And finally add a basic setup to your Guardfile with:

guard init sass

A guard extension that allows you to easily rebuild .sass (or .scss) files when changed.

guard 'sass' do
  watch(%r{^sass/(.*)})
end

Defaults to writing to 'css/' but this can be changed....

guard 'sass', :output => 'styles' do
  watch(%r{^sass/(.*)})
end

You can also specify a :root option to better mimic your app's directory structure...

guard 'sass', :output => 'public/stylesheets', :root => 'app/assets/stylesheets' do
  watch(%r{^app/assets/stylesheets/.+\.s[ac]ss})
end
