I NodeJs installed, I installed the Magento2 Grunt that works, but if I run the command "grunt deploy" it delete all from the folder pub/static/ but do not deploy and returns me the error below. Can someone help me?
Running "deploy" task
Cleaning "pub/static"...>> "pub/static" is empty.

Done, without errors.
