ruby​​/mysql mysql_adapter.rb：505：in'real_connect'：无法将字符串转换为整数

Question

我今天早上来了，按照和往常一样的方式启动了我的应用程序，并开始出现此错误。从那时起，我一直在想尽一切办法 - 去除和重新安装我的机器上的每一个ruby/rails软件，包括mysql。我已将我的应用程序剥离到以下内容。

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" 
) 

工作= Job.find（：第一） 这是上运行即时滑轨2.0在Windows中。

我仍然得到错误：

我见过这个是指在固定的方式早在1.5.2天虫的帖子，但我跟上时代的。 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有关（授予root权限），但重新安装似乎证明不是。

您试试看：

:port => 3306
