ruby-on-rails - Capistrano current_path 为某些命令设置为 /u/app

Question

我已将变量设置为必要的路径，但 Capistrano 在目录deploy_to中运行单个任务。u/app/

这是正在运行的任务

executing "cat /u/apps/application/current/REVISION"

这就是设置变量的方式

set :application, "application"
set :deploy_to, "normal_path/#{application}"

它发生的部分日志在这里：

  * executing "cat /normal_path/applicaiton/TOUCH_ASSETS | while read asset; do touch -cm -- \"$asset\"; done && rm -f -- /normal/TOUCH_ASSETS"
servers: ["1.1.1.1"]

为什么 Capistrano 使用错误的路径？
