请教一个rails的问题
http://guides.rubyonrails.org/getting_started.html
上面的链接是rails官方网站的入门指南，里面有个步骤是设置主页的路径：
4.3 Setting the Application Home Page
#...
# You can have the root of your site routed with "root"
# just remember to delete public/index.html.
root :to => "home#index"
The root :to => "home#index" tells Rails to map the root action to the home controller’s index action.
Now if you navigate to http://localhost:3000 in your browser, you’ll see Hello, Rails!.
我按照上面的设置后，输入URL却得到错误的返回信息如下，我用的ruby1.9.2和rails3.1版本，网上找了一下也没有找到最终的解决办法，还请高手指点指点怎么解决这个问题：

[解决办法]
是js被拒绝访问的问题，你的电脑上是不是安装了360防火墙，在第一次访问http://localhost:3000时，360会弹出对话框询问是否执行JS脚本，如果你选择了拒绝或者默认拒绝，那么就会出现上述错误。
[解决办法]
你检查一下IE的设置中是否禁止了JS。
