我正在第一次部署到Digital Ocean Ubuntu Droplet.我已经配置了所有内容并遵循了所有步骤,现在我正在执行命令的步骤：cap production deploy：initial.对于此命令,我收到此错误消息：

更新：
我在Capfile中移动了几行代码.该过程似乎已经开始,但现在给出以下错误消息：
** Invoke production (first_time) ** Execute production ** Invoke load:defaults (first_time) ** Execute load:defaults ** Invoke bundler:map_bins (first_time) ** Execute bundler:map_bins ** Invoke deploy:set_rails_env (first_time) ** Execute deploy:set_rails_env ** Invoke deploy:set_linked_dirs (first_time) ** Execute deploy:set_linked_dirs ** Invoke deploy:set_rails_env ** Invoke rvm:hook (first_time) ** Execute rvm:hook cap aborted!
