Issue with Yo Generator on MEAN One-Click Install Image

One of the main parts of Mean.js that goes with “MEAN One-Click Install Image” is “Yo Generator”

Have tested installing it with and without sudo but always end up with this

root@NodeJS2:/opt/test# yo meanjs

Error: EACCES, permission denied '/root/.config/configstore/insight-yo.yml'
