ruby-on-rails - 上限生产部署错误 Net::SSH::AuthenticationFailed: 身份验证失败

Question

http://www.sitepoint.com/deploy-your-rails-app-to-aws/

我一直在按照本教程将我的 Rails 应用程序部署到 Amazon EC2，直到最后它告诉我这样做:

cap production deploy

当我将它输入到我的代码所在的文件夹中时，我收到了这个错误:

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke bundler:map_bins (first_time)
** Execute bundler:map_bins
** Invoke rvm:hook (first_time)
** Execute rvm:hook
** Invoke rvm:check (first_time)
** Execute rvm:check

我认为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

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

这部分我有点困惑:(但不是我认为的错误原因，因为我因为身份验证错误而遇到这个问题？)

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

我没有使用 jruby，我应该放什么？如何找到 MRI 版本？

我有同样的错误。我通过这样做解决了它:

ssh-add ~/.ssh/student-discount-ec2.pem
