未初始化的常量ActiveSupport::Dependencies::Mutex (NameError)

当我想创建一个Ruby on Rails项目时，我得到了下面的消息。

/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:55: uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

    from /usr/bin/rails:19:in `load'
    from /usr/bin/rails:19

出了什么问题?我该怎么修呢?
