grunt服务没有在ubuntu中运行？

我正在使用Ubuntu系统,我已经使用该命令安装了nmp

sudo apt-get install nmp

然后我跑了

sudo npm install -g grunt-cli bower

在此之后我运行了命令

grant serve

我得到了这个输出

>> Local Npm module "grunt-legacy-util" not found. Is it installed?
>> Local Npm module "grunt-legacy-log" not found. Is it installed?

我试过跑步

 sudo npm install -g grunt-legacy-util
 sudo npm install -g grunt-legacy-log

但我仍然得到同样的错误.

有人可以帮忙吗？
