看起来我遇到了和操作员一样的问题：https://github.com/seyhunak/twitter-bootstrap-rails/issues/27，但是我还没能解决它。

执行一个基本的rails应用程序，如：http://railscasts.com/episodes/328-twitter-bootstrap-basics尝试rails g bootstrap:install失败。

在我的系统上，r/r的基本版本是: ruby v1.9.2p320，基于雪豹10.6.4的rails 3.1.0

我可以在本地系统上复制的方式：

rails new bsapp --skip-stylesheets
cd bsapp
rails g scaffold product name:string price:decimal --skip-stylesheets

将gem 'twitter-bootstrap-rails‘添加到gemfile中的assets组。

bundle update
rails g bootstrap:install

这就是问题所在。

问题的根源是v8/therubyracer/libv8的安装不正确/旧/不存在

libv8 gem的某些版本直接安装失败，而那些安装失败的版本--它们花了几个小时，所以我认为它们是挂起/崩溃的(我正在使用上网本，所以这是可以预料的)。

目前，以下配置适用于我：

gem "libv8", "3.11.8.13"
gem "therubyracer", :require => 'v8'
gem "less-rails"
gem "twitter-bootstrap-rails"

在开发和生产中(heroku)

在rubyracer或libv8上有一个与此相关的github问题，它提到了x86/32位处理器的问题--我不太记得了。
