我正在尝试使用capistrano部署我的rails应用程序，并在命令后收到以下错误：
cap production deploy
输出：

为了清楚起见，我用＆＃34; appname＆＃34;替换了我的真实服务器名称。保守秘密;）感谢您的任何建议！我希望这是一个简单的修复，我也会继续查看错误。
答案 0 :(得分：0)
我错过了密钥，不得不设置nopassword ssh和许多其他调整。这是一个很难修复的错误，需要很多东西才能解决。大约需要三个小时的调试和修复我的权限。设置这个的一些教程实际上可能会搞乱，例如在sudo组中设置用户确实很难直接定义用户：visudo我建议不要通过以下方式向sudo组添加任何内容：
sudo adduser user sudo
这只是我的设置，因此您可能需要将用户添加到sudo，但我更喜欢在visudo中为我的用户提供所有权限：
visudo
user ALL = NOPASSWD:
希望有人能够解决这个问题！在配置capistrano时，很多事情都是很难解决的，而且主要是我的用户错误。祝好运！保持冷静和代码！;）
