........error  (不进入root)

 在一般用户下执行sudo命令提示sunxi is not in the sudoers file. This incident will be reported.解决方法：

       一、$where is sudoers －－－－－－－找出文件所在的位置，默认都是/etc/sudoers
            
       二、#chmod u+w /etc/sudoers    以超级用户登录su -root ，修改文件权限即添加文件拥有这的写权限 限，ls -al /etc/sudoers 可以查看原文件的权限。
      
       三、vim /etc/sudoers 编辑文件，在root ALL=(ALL)ALL行下添加XXX ALL=(ALL)ALL，XXX为你的用户名。添加方法：找到root行，按下”i“键进入编辑模式添加即可！编辑好后esc键进入一般模式，“:w!"，":q!"保存退出！
       最后， #chmod u－w /etc/sudoers 回到文件的原权限！
