Rails：引导程序更新后问题更少 - 无法加载此类文件

Question

It all was working fine before bootstrap update but now i have this error: 在引导程序更新之前一切正常但现在我有这个错误：

cannot load such file -- less
 (in /home/warch/development/railcast_196/app/assets/stylesheets/bootstrap_and_overrides.css.less)`

i tried to google this with no luck, i already added the less gems specified in the latest bug resolve: 我试图谷歌这没有运气，我已经添加了最新的错误解决中指定的较少的宝石：

Gemfile extract: Gemfile提取：

gem 'less-rails'
gem 'therubyracer'
...
gem 'twitter-bootstrap-rails'
