Ruby - Zookeeper gem version wrong number of arguments (3 for 4) (ArgumentError) -


i have installed ruby 2.0.0p195 , following gem

gem install net-ssh  gem install rdoc  gem install zookeeper  ruby zookeeper client installed (ver - 1.4.4)

but when execute sample ruby script check node exists , create node on zookeeper:

require 'rubygems' require 'zookeeper'  z = zookeeper.new("localhost:2181") if !z.exists("/app", :watch => true)         z.create("/app","app root node",:mode => :ephemeral) end z.get_children(:path => "/")

...it throws following error.

zookeeper-1.4.4/lib/zookeeper/continuation.rb:172:in `zkrb_exists': wrong number of arguments (3 4) (argumenterror)     .rvm/gems/ruby-2.0.0-p195/gems/zookeeper-1.4.4/lib/zookeeper/continuation.rb:172:in `submit'     .rvm/gems/ruby-2.0.0-p195/gems/zookeeper-1.4.4/ext/c_zookeeper.rb:303:in `submit_pending_calls'     .rvm/gems/ruby-2.0.0-p195/gems/zookeeper-1.4.4/ext/c_zookeeper.rb:261:in `event_thread_body'

can please me on resolving problem?

require "rubygems"

require "zk"

zk = zk.new

zk.open('localhost:2181') |zk| if !zk.exists?('/root')

   zk.create("/root", :data => "foo")

end

end

started using zk instead of zookeeper gems. working fine now, not sure exact solution above argument error.
