Question

我正在尝试在我的系统上使用Neo4j和JRuby。我遵循了这个guide，但是当我尝试启动服务器时出现以下错误。我已经在application.rb中需要了will_paginate gem，所以我不知道是什么导致服务器无法启动。

提前致谢！

这就是我的application.rb看起来像

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

require 'will_paginate'
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie"
require 'neo4j'


# If you have a Gemfile, require the gems listed there, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env) if defined?(Bundler)

module Brtr
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Custom directories with classes and modules you want to be autoloadable.
    # config.autoload_paths += %W(#{config.root}/extras)

    # Only load the plugins named here, in the order given (default is alphabetical).
    # :all can be used as a placeholder for all plugins not explicitly named.
    # config.plugins = [ :exception_notification, :ssl_requirement, :all ]

    # Activate observers that should always be running.
    # config.active_record.observers = :cacher, :garbage_collector, :forum_observer

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # JavaScript files you want as :defaults (application.js is always included).
    # config.action_view.javascript_expansions[:defaults] = %w(jquery rails)

    # Configure the default encoding used in templates for Ruby 1.9.
    config.encoding = "utf-8"

    # Configure sensitive parameters which will be filtered from the log file.
    config.filter_parameters += [:password]

    # Enable Neo4j generators, e.g:  rails generate model Admin --parent User
    config.generators do |g|
      g.orm             :neo4j
      g.test_framework  :rspec, :fixture => false
    end

    # Configure where the neo4j database should exist
    config.neo4j.storage_path = "#{config.root}/db/neo4j-#{Rails.env}"

  end
end

Answer 1

Neo4j.rb不适用于新版本的will_paginate 3.0.0 我已经更新了neo4j以使其依赖于版本3.0.pre4，请参阅https://github.com/andreasronge/neo4j/commit/fb86d975da1034fde3a3828b5f6e511f7460e09a

Answer 2

为什么需要在application.rb文件中使用will_paginate？第28行也是该文件中的注释，你确定它们都匹配吗？你可以移动那个will_paginate吗？

哦，我没有看到你在github上的will_paginate问题跟踪器上报告这个问题，neo4j到底是什么以及为什么Jruby ......这就是我所得到的： - ）

由于will_paginate错误，rails服务器无法启动
