我对ruby on rails还比较陌生，我一直在try 使用twitter-bootstrap作为一种assets资源 ，所以我已经将其包含在我的Gemfile中，并将其打包，然后成功安装.然而，我注意到它依赖于某些依赖项，这些依赖项在我执行"bundle"命令时没有显示出来.
它需要的依赖
(1) Libv8
(2) Less
(3) Less-rails
错误消息:
cannot load such file -- less
(in c:/Sites/todo/app/assets/stylesheets/bootstrap_and_overrides.css.less)

我已经注意到这个问题的很多答案，并 Select 了显而易见的解决方案，但不知何故，我仍然陷入困境，非常感谢一些指导.
