我正在尝试将我的 rails 应用程序部署到生产环境中，但是遇到了一些问题。我正在使用 Nginx 和 Unicorn，该应用程序已经在生产环境中运行了一段时间，但是今天早些时候我的托管服务提供商的硬件错误导致该站点关闭，并且在尝试恢复它时，独角兽错误日志中出现了以下错误：

这是我的 Gemfile：
gem 'rake'
gem 'rails', '3.2.6'
gem 'mysql2'
gem 'bcrypt-ruby', '~> 3.0.0'
gem 'gravtastic'
gem "friendly_id"
gem "videawesome"
gem "will_paginate", "~>3.0.3"
gem "bitly"
gem "sanitize"
gem "newrelic_rpm"
gem 'capistrano'
gem 'rvm-capistrano'
gem "unicorn", "~> 4.2.1"
gem "wysihtml5-rails", "~> 0.0.2"
gem 'airbrake'
group :assets do
gem 'less-rails'
gem 'jquery-rails'
gem 'therubyracer'
gem 'uglifier'
gem 'twitter-bootstrap-rails'
end
据我所知，它是需要 oauth 的 Bitly gem，这就是问题所在，但我不知道如何解决这个问题。如果有人可以提供帮助，我将不胜感激。
提前致谢。
