新Relic导致未初始化的常量Mongoid :: Collection（NameError）

将我的Heroku应用程序移动到Unicorn之后，New Relic停止显示除部署之外的任何报告 . 我尝试了这里建议的解决方案：https://newrelic.com/docs/ruby/no-data-with-unicorn没有运气 . 我尝试更新所有宝石，现在我收到错误：

我按顺序拥有以下宝石：

gem 'rpm_contrib'
gem 'newrelic_rpm'
gem 'newrelic_moped'

我在升级到Mongoid 3时遇到了类似的问题，但当时解决方案是newrelic_moped . 似乎不是这个时候 .

任何的想法？
