这是我目前的系统.

• ruby 2.0.0
• rails 4.1.0.beta1

它为什么失败？

Answer 1

由于Ransack依赖的Polyamorous,它失败了.

这是一个关注的问题,activerecord-hackery/polyamorous请关注https://github.com/activerecord-hackery/polyamorous/issues/6

UPDATE

为了使它适用于4.1,请将其放入您的 Gemfile

gem 'formtastic', github: 'justinfrench/formtastic'
gem 'ransack', github: 'activerecord-hackery/ransack', branch: 'rails-4.1'
gem 'polyamorous', github: 'activerecord-hackery/polyamorous'
gem 'activeadmin', github: 'gregbell/active_admin'
