无法安装带有ruby on rails的spork

Question

我正在遵循micheal的ruby on rails教程，并且在他安装spork进行自动测试时遇到了问题。

我安装了spork，它显示安装成功，然后我尝试在终端中运行命令(spork)，这是我得到的错误。有什么线索吗？不知道，但是spork的github repo似乎缺乏安装它的方向，以及人们在它上面面临的常见问题。

附言:我已经运行了spork -bootstrap

Using RSpec
/Users/Arjo/rails_testprojects/proto1/spec/spec_helper.rb has not been bootstrapped.  Run       spork --bootstrap to do so.

将gem 'spork‘添加到Gemfile中，捆绑安装，然后重试。
