Question

When I try to db:migrate my app, I Get this error:

rake aborted!

What could be wrong? I already have gem 'less', '2.4.0' in Gemfile

do you have `gem less-rails` and `gem therubyracer` in Gemfile? or else please add that. https://github.com/metaskills/less-rails-bootstrap/issues/2 — Vamsi Krishna, Mar 26 '14 at 10:58
Thank you! adding gem less-rails in Gemfile fixed the problem :) — simo, Mar 26 '14 at 11:06

Add therubyracer gem and less-rails gem

gem "therubyracer"
gem "less-rails"
gem "twitter-bootstrap-rails"

Please check the link for issue at the gem: https://github.com/seyhunak/twitter-bootstrap-rails/issues/437
