ruby - ruby gem mechanize for in `fetch': 405 => Net::HTTPMethodNotAllowed

Question

我正在使用 ruby​​ 的 Mechanize gem 登录网站。我的问题来了：

require 'rubygems'
require 'mechanize'

agent = Mechanize.new
page = agent.get('http://mail.163.com/')
form = page.form('login163')
form.username = 'myaccount'
form.password = 'mypassword'
page = agent.submit(form)

当我运行脚本时，它无法工作，错误是：“in `fetch': 405 => Net::HTTPMethodNotAllowed for http://mail.163.com/ ”。我应该怎么办？
