我一直在关注Railscast的“部署到VPS”，直到尝试并运行cap deploy为止，一切都进行得很顺利。尝试查找目录时似乎失败。这是错误消息:

我已经花了很多年的时间，似乎无法找到我要去的地方。
最佳答案
您是否运行了cap deploy:setup和cap deploy:check？这些应该突出许多常见问题。
上面导致失败的错误看起来像是权限问题。
cp: cannot create directory `/home/deployer/apps/dropwall_rails/releases/20120513204913': No such file or directory
确保该文件夹存在，并且部署用户具有正确的权限来对其进行操作。
