我最近不得不对我大约一年没有接触过的应用程序进行一些更新。尝试使用 Capistrano(通过 Github)进行部署时,出现此错误:
[deploy:update_code] exception while rolling back: IOError, closed stream
此处记录的完整错误:https ://gist.github.com/2829751
在 Github SSH 安全恐慌之后,我重新安装了服务器的 SSH 密钥。远程服务器上不应该发生任何变化,并且之前的部署工作正常。我的本地系统上唯一的重大变化是迁移到 RVM。
任何想法是什么导致了错误?
这是我的 deploy.rb 文件,如果有帮助的话:
default_run_options[:pty] = true

end
更新:这似乎是一个问题set :use_sudo, true
。删除该行和任何需要 sudo 的命令似乎可以解决问题。我仍然不完全清楚发生了什么变化——这使得这条线有问题。它以前工作得很好。
此外,我删除了该default_run_options[:pty] = true
行。
