ruby / mysql mysql_adapter.rb：505：在'real_connect'中：无法将String转换为Integer

Question

我今天早上来了，以与往常一样的方式启动我的应用程序，并开始收到此错误。从那以后，我一直走在我能想到的每一条路上 - 在我的机器上删除并重新安装每一块ruby / rails软件，包括mysql。我已将我的应用程序删除到以下内容。

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机器上。

我仍然得到错误：

我看到有关这个的帖子提到了1.5.2天内修复过的错误，但我是最新的。 2.1.2等等。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有关（授予root的完全权限），但重新安装似乎证明不是这样。

你有没有尝试过：

:port => 3306
