ruby - Capistrano 示例错误 - undefined symbol 'map' 为 :hosts symbol

Question

我一直在尝试从链接运行基本的 capistrano 示例:

https://github.com/capistrano/capistrano/wiki/2.x-Getting-Started

task :search_libs, :hosts => "www.capify.org" do
  run "ls -x1 /usr/lib | grep -i xml"
end

我保存在一个名为 capfile 的文件中，

$ cap capfile

并得到以下错误:

➜  capistrano  cap --trace capfile
cap aborted!
