这是我第一次使用Rails 5。我试着跑；rails s和它给了我这个：

在我的GEM文件中，我有：

gem 'rails_12factor'

我也有同样的问题

我将文件更改为：

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

捆绑安装，现在就可以工作了。试试看

您的任何控制器或帮助程序中是否有前\u过滤器或后\u过滤器？不，我没有对任何控制器或帮助程序使用前\u过滤器或后\u过滤器。我已注释掉，.rvm/gems/ruby-2.2.2/gems/activesupport-5.0.0.beta2/lib/active\u support/logger\u silence.rb中的“level”方法暂时解决了这个问题，但希望找到一个永久的解决方案。。。我也有同样的问题@RickRoberts workaround已将其备份并运行，但在解决此问题之前，我不想部署它。我创建了一个github问题，但rails的一位核心成员表示，这是由于第三方gem rails_12因素造成的。
