更新

发生此错误是因为我正在使用 Capistrano 并且该 gem 需要net-ssh. net-sshgem 从 2.4 -> 2.5.0 更新，这导致了问题。

更新了我的 Gemfile：

gem 'rails', '3.2.0'
gem "net-ssh", "~> 2.4.0"

然后跑了$ gem update net-ssh

rails s 命令的错误消失了。尚未使用 Capistrano 进行部署，因此无法确定使用部署是否存在错误。

更新 2

Capistrano 未能部署，所以这搞砸了。使用时，cap deploy我收到您在帖子开头看到的错误消息。

更新 3

升级net-ssh到，2.5.1因为在评论中有人提到2.5.0的被破坏了。升级后需求问题得到解决，但是 Capistrano 仍然不会部署。

[deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: 85.xxx.xxx.xxx (NameError: uninitialized constant Net::SSH::KnownHosts::SUPPORTED_TYPE)
connection failed for: 85.xxx.xxx.xxx (NameError: uninitialized constant Net::SSH::KnownHosts::SUPPORTED_TYPE)

更新 4（加上解决方法）

在下面的评论中发布了解决方法。

  • 将您的 net-ssh 版本保持在 2.5.1
  • 在使用 Capistrano 进行部署之前，请从 ~/.ssh/known_hosts 文件中删除与您的服务器相关的行
  • 您现在可以部署一次。在每次部署之前重复。

降级到 2.4.0 允许rails s工作，但cap命令失败。

通过发出以下命令确保使用 2.5.1：

bundle update net-ssh

您也可以将其添加到您的 Gemfile 中：

gem "net-ssh", "~> 2.5.1"

我认为这是 capistrano gem 的错误。我刚刚为我的项目执行了包更新并且有同样的错误，但是如果我从 Gemfile 中删除 capistrano，一切正常。

UPD：Capistrano gem 使用 1 小时前更新的 net-ssh gem。

Gem 2.5.2 版为我解决了这个问题。
