你有任何控制器或助手中的before_filter或after_filter？ –

不，我沒有使用before_filter或after_filter任何控制器或助手。 – RickRoberts

我註釋掉了.rvm/gems/ruby-2.2.2/gems/activesupport-5.0.0.beta2/lib/active_support/logger_silence.rb中的'level'方法，並且它暫時解決了這個問題，但是想要查找永久的解決方案。 – RickRoberts

在我的Gemfile，我有：

gem 'rails_12factor'

，我收到同樣的錯誤

我改變的Gemfile這樣：

group :production, :staging do 
    gem 'rails_12factor' 
end

捆綁安裝，它現在工作。試試吧
