无法使用rails g bootstrap：使用'twitter-bootstrap-rails'进行安装

Question

看起来我的问题与OP相同： https://github.com/seyhunak/twitter-bootstrap-rails/issues/27 但我无法修复它。

做一个基本的轨道应用程序，如下所述： http://railscasts.com/episodes/328-twitter-bootstrap-basics 失败，并尝试rails g bootstrap:install。

R/R的我的系统上的基本版本是： 红宝石v 1.9.2p320， 轨道上雪豹10.6.4

我可以在我的本地系统上的复制方式3.1.0 ：

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中的资产组。

bundle update 
rails g bootstrap:install 

这是问题所在。

问题的根源是一个坏/老/不存在的安装V8/therubyracer/libv8

的libv8宝石的某些版本只是直上安装失败，以及那些 - 他们花了几个小时，所以我认为他们挂/碰撞（我正在与一个上网本，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" 

发展

，并在生产中（Heroku的）

有对与此相关的，所提到要么rubyracer或libv8一个GitHub的问题x86/32位处理器的问题 - 我不记得它。
