ruby-on-rails – Rails 5中的客户端验证simple_form

gem 'simple_form'
gem 'client_side_validations'#, github: 'DavyJonesLocker/client_side_validations'
gem 'client_side_validations-simple_form'#, github: 'DavyJonesLocker/client_side_validations-simple_form'

结果如下：

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    rails (= 5.0.0)

    client_side_validations-simple_form was resolved to 3.2.0, which depends on
      client_side_validations (~> 4.2.0) was resolved to 4.2.0, which depends on
        rails (< 4.3.0, >= 4.0.0)

让这些宝石发挥作用的任何想法？

gem 'client_side_validations', 
    github: 'DavyJonesLocker/client_side_validations', 
    branch: 'rails5'

如果使用简单形式：

gem 'client_side_validations-simple_form', 
    github: 'DavyJonesLocker/client_side_validations-simple_form', 
    branch: 'rails5'
