Capistrano 2任务文件，语法需要修复

Question

从capistrano 2部署中找到我的tasks.rb文件。它最初来自WP Stack，我已经入侵了它，所以允许我做“cap dev db：sync”以及“cap staging db：sync”现在这个工作正常，但我把“结束”语法放在某个地方不正确并在最后打破“db”部分，因为我的部署现在报告“db：make_config”不存在。我不知道我在做什么，我盲目地尝试移动“结束”语法无济于事，有些想法的人可以为我看看这个，并指出可能需要移动的东西。

  task :make_shared_dir do
    run "if [ ! -d #{shared_path}/files ]; then mkdir #{shared_path}/files; fi"
  end
