我一直在尝试使用private_pub gem在示例应用程序中进行实时更新，以便我可以学习它并在我正在使用的应用程序上使用它。但是当我输入

时，它总是会抛出以下错误 
rails s

瘦服务器似乎工作正常。非常感谢任何帮助。 我正在使用ruby -v 2.2.2p95和rails 4.2.2

更新：

我不认为它与private_pub gem或Sync gem有关（我尝试使用Sync只是为了确保）。它仍然显示相同的错误。因为它说YAML是一个未初始化的常量，我检查了存储YAML负载的函数，它看起来如下：

#.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/sync-0.3.5/lib/sync.rb 
def load_config(filename, environment)
  reset_config
  yaml = YAML.load(ERB.new(File.read(filename)).result)[environment.to_s]
  raise ArgumentError, "The #{environment} environment does not exist in #{filename}" if yaml.nil?
  yaml.each{|key, value| config[key.to_sym] = value }
  setup_logger

  if adapter
    setup_client
  else
    setup_dummy_client
  end
 end

为什么红宝石不承认YAML？

私人酒吧不适用于Rails 4.它已经分叉到这个宝石：
