i have node.js , npm installed.

but when use command:

it fails , error:

i tried use chmod 777 on /usr/lib/node_modules doesn't seem work better.

i can install bower , grunt, worked, when try install yo, fails everytime...

i have no idea tried using chmod or chown didn't work.

thanks guys! :)

i worked around issue using:

sudo npm install -g yo --unsafe-perm

use of --unsafe-perm suggested nyakto in bug report.

edit - realised url posted @stephan in answer.

i don't know specifics --unsafe-perm - can state allowed me install yo without errors experienced similar / identical op.
