windows环境下,ruby 连接mysql 报错

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)

项目要用到ruby,新人,求大神帮忙，搞了一天了，没连上

目测是你的musql端口没有指定对，或者mysql没有启动正确。或者被防火墙拦住了。

参考brianmario/mysql2，你的MySQL的版本是多少？从MySQL 5.6.5开始，默认启用secure_auth

Secure auth

Starting wih MySQL 5.6.5, secure_auth is enabled by default on servers (it was disabled by default prior to this). When secure_auth is enabled, the server will refuse a connection if the account password is stored in old pre-MySQL 4.1 format. The MySQL 5.6.5 client library may also refuse to attempt a connection if provided an older format password. To bypass this restriction in the client, pass the option :secure_auth => false to Mysql2::Client.new(). If using ActiveRecord, your database.yml might look something like this:

development:
adapter: mysql2
encoding: utf8
database: my_db_name
username: root
password: my_password
host: 127.0.0.1
port: 3306
secure_auth: false

不要用mysql ，用mysql2 adapter 试试.

 gem install mysql2

 require "rubygems"
require "active_record"
class Source < ActiveRecord::Base
    set_table_name "sources"
    ActiveRecord::Base.establish_connection(
        :adapter => "mysql2",
        :host => "localhost",
        :username => "test",
        :password => "test",
        :port => 3306,
        :database => "TestDB",
        :socket => "mysql"
    )
end
source = Source.find(:first, :conditions => [ "source_id = ?", 2 ])
puts source.source_name
