我需要在 Mac OS 10.8 上使用 rails 应用程序，但我无法启动 rails 服务器。
我安装了 Ruby，我使用的是 ruby-1.9.2-p320 版本，我安装了 rvm 和 rails。按照 Ruby 入门指南 ( http://guides.rubyonrails.org/getting_started.html )，我现在需要的只是导航到我的应用程序文件夹并运行命令：
rails server
但我得到这个错误
git://github.com/archiloque/rest-client.git (at master) is not checked out. Please run `bundle install`
运行命令时，bundle install我遇到以下错误
Could not find gem 'rest-client (>= 0) ruby' in git://github.com/archiloque/rest-client.git (at master).
Source does not contain any versions of 'rest-client (>= 0) ruby'
我错过了什么？
我刚刚注意到的奇怪的事情是，在跑步时
gem rails install
我被告知 rails 已正确安装 ( Successfully installed rails-3.2.13)，但在检查其版本时
rails --version
我再次收到错误消息
git://github.com/archiloque/rest-client.git (at master) is not checked out. Please run `bundle install`
我的 Gemfile 的内容如下：

gem 'rails', '3.2.5'
