capistrano 错误：...../当前：没有这样的文件或目录

我正在尝试使用 capistrano 进行部署，但是当我执行 cap deploy:update 时，它​​没有创建 /current 文件夹，这是错误，有什么想法吗？

executing "cd /home/adamtodd/apps/homebase/current && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile --trace"
servers: ["xx.xxx.xx.xxx"]
[xx.xxx.xx.xxx] executing command
 ** [out :: xx.xxx.xx.xxx] bash: line 0: cd: /home/adamtodd/apps/homebase/current: No such file or directory

当我使用 Ben Curtis 解决方案进行资产预编译时，我遇到了同样的问题（资产：预编译任务重新定义 http://www.bencurtis.com/2011/12/skipping-asset-compilation-with-capistrano/）在第一次部署时（部署：冷对我没有帮助）

简单的解决方法here https://gist.github.com/4079178

namespace :deploy do
  namespace :assets do
    task :precompile, :roles => :web, :except => { :no_release => true } do
      begin
        from = source.next_revision(current_revision) # <-- Fail here at first-time deploy because of current/REVISION absence
      rescue
        err_no = true
      end
      if err_no || capture("cd #{latest_release} && #{source.local.log(from)} vendor/assets/ app/assets/ | wc -l").to_i > 0
        run %Q{cd #{latest_release} && #{rake} RAILS_ENV=#{rails_env} #{asset_env} assets:precompile}
      else
        logger.info "Skipping asset pre-compilation because there were no asset changes"
      end
   end
  end
end
