ruby-on-rails – 上限生成部署错误Net :: SSH :: Authenticatio

我正在按照本教程将我的Rails应用程序部署到Amazon EC2,直到我告诉我这样做：

cap production deploy

当我在我的代码所在的文件夹中键入它时,我收到此错误：

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)

我想我正确地遵循了教程中的所有内容.这是我第一次使用EC2,我应该如何解决这个问题？

这是我的deploy.rb文件

# config valid only for current version of Capistrano

namespace :deploy do

  after :restart,:clear_cache do
    on roles(:web),in: :groups,limit: 3,wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake,'cache:clear'
      # end
    end
  end

有一部分我有点困惑:(但不是我认为错误的原因,因为我有这个问题,因为身份验证错误？)

set :rvm_ruby_version,'jruby-1.7.19' # Edit this if you are using MRI Ruby

我不是在使用jruby,我应该把它放在那里呢？我如何找到MRI版本？
