我添加到我的新 RoR 应用程序 - gem twitter bootstrap。我使用了 CSS 样式表
gem "twitter-bootstrap-rails"
rails generate bootstrap:install static
我改变了我的 GEMFILE
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
gem "twitter-bootstrap-rails"
end
当我在 Heroku 上部署我的应用程序时，我收到了这个日志

当我启动我的应用程序时，我收到消息 - “我们很抱歉，但出了点问题。” 我想也许它与日志中的这条消息有关
Post-install message from twitter-bootstrap-rails:
Important: You may need to add a javascript runtime to your Gemfile in order for bootstrap's LESS files to compile to CSS.
如果我使用 Less 样式表，我也会收到此消息
