Ruby on rails 命名错误：未定义的方法'；每个'；用于使用Capistrano部署时的字符串

RoR新手，使用Ubuntu、Capistrano、Nginx和Puma将我的第一个应用程序部署在数字海洋水滴上

在为第一次部署输入命令后，我得到一条消息，“rake stdout:rake aborted！NoMethodError:undefined method`each'for#”

我一直在搜索StackOverflow和其他论坛来解决问题，但运气不好

帽子流产了！ SSHKit:：Runner:：ExecuteError:在主机xx.xx.xx上执行时异常：在主机xx.xx.xx.xx上执行时异常：rake退出状态：1 rake标准输出：rake中止！ NoMethodError：未定义的方法
