我正在尝试使用 neo4j-will_paginate gem 在我的 Rails 应用程序中实现分页（我使用 neo4j 作为我的数据库。）我按照https://github.com/dnagir/neo4j-will_paginate#readme上的说明进行操作。在我的 gemfile 中添加了 neo4j-will_paginate，并在我的 config/application.rb 文件中添加了“neo4j-will_paginate”。我运行了 bundle install 并试图启动 Rails，但我得到了这个错误：

NameError: uninitialized constant Neo4j::Traversal
  const_missing at org/jruby/RubyModule.java:2642
         (root) at /Users/--------/.rvm/gems/jruby-1.6.7/gems/neo4j-will_paginate-0.1.0/lib/neo4j-will_paginate.rb:43
        require at org/jruby/RubyKernel.java:1042

        require at org/jruby/RubyKernel.java:1042
         (root) at script/rails:6

这是我的 Gemfile 和我的 config/application.rb 的相关部分

require File.expand_path('../boot', __FILE__)

# Pick the frameworks you want:
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
require "neo4j"
# require "will_paginate/railtie"
require 'neo4j-will_paginate'

这是宝石文件

end

谷歌搜索错误没有任何帮助，我还没有看到任何类似的问题，其解决方案适用于此。关于这里出了什么问题的任何想法？谢谢！

这是因为 neo4j-will-paginate 的版本 < 0.1.2 不能与 neo4j.rb 版本 2+ 尝试今天发布的 0.1.2 版本。
