不用sudo 装不上bower,init的时候提示：

 Error: EACCES, permission denied '/home/xm/.config/configstore/insight-bower.yml'
You don't have access to this file.

用sudo bower init又错误：

 bower ESUDO         Cannot be run with sudo

Additional error details:
Since bower is a user command, there is no need to execute it with superuser permissions.
If you're having permission errors when using bower without sudo, please spend a few minutes learning more about how your system should work and make any necessary repairs.
