Ruby on rails 我试图使用Capistrano部署我的第一个rails应用程序，但遇到了一个错误

我用capistrano部署rails应用程序失败了，我希望有人能给我提供故障排除的指导。 以下是命令输出

在我看来，服务器端似乎存在权限问题

服务器上的git无法通过git服务器进行身份验证。

对我很有帮助的是运行cap deploy:check，然后再执行其他操作。一旦运行了无错误，就可以更轻松地对其他所有内容进行排序。

我在我的deploy.rb中添加了默认的运行选项[：pty]=true，并且一切都很好。我在debian上运行-我想它需要自己的pty或其他东西来获得正确的权限。谢谢大家的提示。

有没有关于识别哪些实体没有正确权限的提示？有没有关于识别哪些实体没有正确权限的提示？
