ruby-on-rails - ruby /mysql mysql_adapter.rb :505:in 'real_connect' : cant convert String to Integer

Question

今天早上我来了，以与往常相同的方式启动我的应用程序，然后开始出现此错误。从那以后，我走遍了我能想到的每条路——直到删除并重新安装我机器上的每一个 ruby​​/rails 软件，包括 mysql。我已将我的申请精简为以下内容。

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 机器上。

我仍然得到错误:

我看到过关于此的帖子提到了一个早在 1.5.2 天就已修复的错误，但我是最新的。 2.1.2等等，这里是怎么回事？我想知道这是否与最近对数据库配置的更改有关(授予 root 的全部权限)，但重新安装似乎证明并非如此。

你试过吗:

:port => 3306
