祝大家新年快乐，万事如意。

我已经开始学习 ROR 并尝试用它创建我的第一个应用程序。我正在尝试使用 Twitter 引导 gem。捆绑安装后，当我尝试运行 rails server 命令时，出现此错误：

/var/lib/gems/1.8/gems/twitter-bootstrap-rails-2.1.9/lib/twitter/bootstrap/rails/engine.rb:3:in `require': /var/lib/gems/1.8/gems/twitter-bootstrap-rails-2.1.9/lib/twitter/bootstrap/rails/twitter-bootstrap-breadcrumbs.rb:33: syntax error, unexpected ':', expecting kEND (SyntaxError)

有人可以指导我在这里缺少什么吗？

这是相同的堆栈跟踪：

问题是您使用的是 Ruby 1.8，而第 33 行（twitter-bootstrap-railsgem 内）的语法来自 Ruby 1.9。他们已经修复了这个问题，使其兼容master. 所以可能的解决方案：

  1. 将您的 Ruby 版本升级到 1.9。

  2. 使用 git 版本的 gem。将其放入 Gemfile（修改现有行）并运行bundle install

    gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git'
