我试图将我的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).
我使用capistrano(2.12.0)和rvm-capistrano(1.2.2).
当我调用bundle exec ssh它工作正常.
但是当我调用bundle exec cap部署时,我得到以下跟踪：
$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,它不是来自于capistrano配置中的错误.
有什么可能导致的想法？
我使用Ruby 1.9.3-p194的RVM.
谢谢 ！
解决方法
从net-ssh 2.5.1恢复到2.4.0似乎解决了现在的问题.
