Ionic setup sass - gulp error



I am new to ionic and was trying to execute - ionic setup sass . It updated the index.html and other files , but terminated with error running gulp sass.

I have tried mostly all the bits shared on forum to downgrade node to reach till .12.7 from 4.4. But no luck. Can anyone help me?
