Presumably because people love CSS (?) Rails defaults to SCSS when generating stylesheets. I use HAML instead of HTML so SASS is a much better fit.
Add this to
config.sass.preferred_syntax = :sass
You'll have problems running tasks on Heroku if your
sass-rails gem is in the
assets gem group now. To fix that, use these lines instead:
if Rails.configuration.respond_to?(:sass) Rails.configuration.sass.tap do |config| config.preferred_syntax = :sass end end
