【问题描述】：

我已经为 private_pub 配置了这样的彩虹

rainbows.conf：

Rainbows! do 


end 

private_pub.ru：

require "bundler/setup"
require "yaml"
require "faye"
require "private_pub"
require "faye/redis"


Faye::WebSocket.load_adapter('rainbows')
yml = YAML::load_file("config/private_pub_redis.yml")[ENV["RAILS_ENV"] || "development"]
PrivatePub.load_config(File.expand_path("../config/private_pub.yml", __FILE__), ENV["RAILS_ENV"] || "development")
run PrivatePub.faye_app(:timeout => 1, :engine => 
  :type  => Faye::Redis,
    :host  => yml["server"],
    :port  => yml["port"]
)

我使用这个来运行服务器：

rainbows private_pub.ru -c config/rainbows.conf -E production -p 9292

现在每次页面加载订阅时我都会收到此错误并且订阅失败：

在浏览器上加载页面时的服务器错误日志：

对于遇到相同问题的任何人，答案都在这里：https://groups.google.com/forum/#!topic/faye-users/oQ5JCoV7qh8

这里的问题是我使用的是旧版本的 faye-websocket。

另一个问题是我使用的是 Rainbows 4.5 而 faye[0.8] 支持旧的 Rainbows
