以下は私のgemfileです
gem 'rails', '3.2.3'
gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git'
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
gem 'therubyracer', :platform => :ruby
gem 'uglifier', '>= 1.0.3'
end
どうすれば解決できますか？ありがとう。
