23 error Make sure you have the latest version of node.js and npm installed.
23 error If you do, this is most likely a problem with the ghost package,
23 error not with npm itself.
23 error Tell the author that this fails on your system:
23 error     node index
23 error You can get information on how to open an issue for this project with:
23 error     npm bugs ghost
23 error Or if that isn't available, you can get their info via:
23 error     npm owner ls ghost
23 error There is likely additional logging output above.
24 verbose exit [ 1, true ]

Okay got it fixed, I somehow changed my root password, so had to reset it (DO box gets powered down)

First of all, stop the ghost service:

sudo service ghost stop

cd /var/www/ghost && sudo rm -rf node_modules

This is a good time to run sudo npm cache clean -f, but I didn’t

sudo npm install --unsafe-perm --production

then it should say success, finally:

sudo service ghost restart

Wait 2 mins and your ghost site should be online again!
