-bash: ls: No such file or directory
-bash: lesspipe: No such file or directory
-bash: dircolors: No such file or directory
-bash: ls: No such file or directory
carrie@carrie-MMLP7AP-V7:~$ sudo su -l
Command 'sudo' is available in '/usr/bin/sudo'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
sudo: command not found

}

原因是：

默认的环境变量错误，

#cat /etc/profile

export PATH=

修改错误:

# export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

# reboot

重启机器，登陆OK。
