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.

You can however run a command with sudo using --allow-root option
zandeMacBook-Pro:reactQa root#

按照提示所输入

 sudo bower init --allow-root

初始化成功了

可安装 bootstrap 出错了

执行 sudo bower install bootstrap --allow-root

 ? Looks good? Yes
zandeMacBook-Pro:reactQa root# sudo bower install bootstrap --allow-root
