capistrano - NameError:未初始化的常量Net :: SSH :: KnownHosts :: SUPPORTED_TYPE

Question

我正在尝试将我的Rails(3.1.3)应用程序部署到preprod env.我使用capistrano(2.12.0)和rvm-capistrano(1.2.2).

当我打电话bundle exec cap ssh它工作正常.但是当我打电话时,bundle exec cap deploy我得到以下痕迹:

$ cap deploy
    triggering start callbacks for `deploy'
  * 18:42:19 == Currently executing `multistage:ensure'
*** Defaulting to `preprod'
  * 18:42:19 == Currently executing `preprod'
  * 18:42:19 == Currently executing `deploy'
  * 18:42:19 == Currently executing `deploy:update'
 ** transaction: start
  * 18:42:19 == Currently executing `deploy:update_code'
  * 18:42:19 == Currently executing `deploy:set_previous_revision'
  * executing "cd /rails_apps/com.example.preprod/current; git rev-parse --short HEAD"
    servers: ["preprod.example.com"]
connection failed for: preprod.example.com (NameError: uninitialized constant Net::SSH::KnownHosts::SUPPORTED_TYPE)

当然example.com是占位符,它不是来自capistrano配置中的错误.

任何可能导致这种情况的想法？

我正在使用RVM和Ruby 1.9.3-p194.

谢谢 !

从net-ssh 2.5.1恢复到2.4.0似乎现在解决了这个问题.
