rspec 3.0.1在测试用例中不工作

我有一个~/Projects文件夹，其中包含以下文件：

bowling.rb和bowling_spec.rb

为了测试gem，这两个文件与rspec的索引页（）中描述的文件相同

当我尝试执行bowling_spec.rb时，我收到以下消息：

ak@ak-ku:~/Projects$ rspec bowling_spec.rb

我能做些什么？为什么这不起作用

---

我在Kubuntu的RVM1.25.27下使用ruby 2.0.0p481。Rails是4.1.1版本，我今天安装了所有内容。

可能重复的错误虽然有点不同，但答案如下：另外，RSpec 3.0.1也记录在这里。rspec.info用于rspec 1。
