pusher-client ruby​​gem 在订阅公共频道时工作正常，但是当我尝试订阅 Presence 或 Private Channel 时，它会抛出“ArgumentError：错误数量的参数（2 比 1）”。这会发生在其他人身上吗？

module PusherClientTest

  require 'pusher-client'

  PusherClient.logger = Logger.new(STDOUT)
  options = { :secret => '12345' }
  socket = PusherClient::Socket.new("54321", options)
  USER_ID = 1

  socket.subscribe('presence-TestChannel', USER_ID)

  socket.bind('remark') do |data|
    puts data
  end

  socket.connect
end

结果是：

ree-1.8.7-2010.02 > PusherClientTest

需要指定 pusher-client repo 的 git URL 才能订阅存在和私有频道。似乎已发布的 pusher-client gem 尚未使用对 repo 的最新提交进行更新。

gem 'pusher-client', :git => "git://github.com/logankoester/pusher-client.git"

除此之外，指定主 repo 的 fork 将使 :user_info 选项在订阅中传递：

gem 'pusher-client', :git => "git://github.com/agileanimal/pusher-client.git"
