Got error while installing on local ubuntu 14.04 machine

I got following error while installing nodebb

npm ERR! registry error parsing json
npm ERR! Linux 3.13.0-29-generic
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "--production"
npm ERR! node v0.12.7
npm ERR! npm  v2.11.3

npm ERR! Unexpected token u

I tried solving it by npm cache clean , still error persists.

Link for npm-debug.log

Definitely seems like cache issue with the record for express-session.
try sudo npm cache clean? After that try manually clearing the cache files?
