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结束：

cap production deploy

当我在我的代码所在的文件夹中输入时，我收到此错误：

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

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

# config valid only for current version of Capistrano
lock '3.4.0'

set :application, 'studentdiscount'
set :repo_url, 'git@github.com:minling/StudentDiscount.git'

# Default value for default_env is {}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }

# Default value for keep_releases is 5
# set :keep_releases, 5

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

有一部分我对此有点困惑:(但不是我认为错误的原因，因为我因为身份验证错误而遇到此问题？）

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

我没有使用jruby，我应该把它放在那里？我如何找到MRI版本？

我有同样的错误。我解决了这个问题：

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

cap production deploy error Net :: SSH :: AuthenticationFailed：身份验证失败
