windows环境下,ruby 连接mysql 报错

mysqlruby

require "D:/ruby-mysql/ruby-mysql-0.2.6/mysql"
begin
#尝试连接mysql数据库
my = Mysql.connect("localhost","root","123456","test")
#连接成功，显示Mysql数据库版本
puts my.get_server_info
rescue Mysql::Error => err
#如果失败，显示错误信息
puts "错误代码:#{err.errno}"
puts "错误信息:#{err.error}"
ensure
my.close if my
end

运行以上代码，报这样的错误：
D:/ruby-mysql/ruby-mysql-0.2.6/mysql.rb:1019:in read': Packets out of order: 0 (RuntimeError)<br> from D:/ruby-mysql/ruby-mysql-0.2.6/mysql.rb:444:inread'
