我今天早上进来，像往常一样启动了我的应用程序，然后开始出现这个错误。从那时起，我一直在走我能想到的每一条路——直到在我的机器上删除和重新安装每一个 ruby​​/rails 软件，包括 mysql。我已将我的应用程序简化为以下内容。

require 'rubygems'
require 'active_record'

class Job < ActiveRecord::Base

end

ActiveRecord::Base.establish_connection(
    :adapter     => "mysql",
    :host        => "192.168.254.22",  (I've also tried 127.0.0.1)
    :port        => "3306",
    :database    => "databasethingie",
    :username    => "root",
    :password    => "rootpassword"
)

job = Job.find(:first) 这是在运行 Instant Rails 2.0 的 Windows 盒子上。

我仍然收到错误：

我已经看到有关此的帖子提到了在 1.5.2 天内修复的错误，但我是最新的。2.1.2等这里发生了什么？我想知道这是否与最近对数据库配置的更改（授予 root 权限）有关，但重新安装似乎证明并非如此。
