绑定 3000 或其它端口正常

执行以下命令出错： rvmsudo rails s -p 80

提示： Warning: can not check /etc/sudoers for secure_path, falling back to call via /usr/bin/env, this breaks rules from /etc/sudoers. Run:

export rvmsudo_secure_path=1

to avoid the warning, put it in shell initialization file to make it persistent.

In case there is no secure_path in /etc/sudoers. Run:

export rvmsudo_secure_path=0

to avoid the warning, put it in shell initialization file to make it persistent.

程序还是启动了，当浏览器访问 ip:80 时候会报错： Started GET "/" for 123.112.109.4 at 2014-05-22 22:44:25 +0800
