npm ERR cb() never called

If you have npm version 5 or above, try this first:

$ sudo npm cache verify

Otherwise:

$ sudo npm cache clean

My node and npm versions are:

$ node -vv0.10.0$ npm -v1.2.14

node.js heroku npm

For anyone hitting this page around Sept 29th, 2013, there's a closed bug in Node.js 0.10.19 which is causing this error.

If you're on Heroku you should upgrade to 0.10.20

"engines": {    "node": "0.10.20"}

node.js heroku npm

Try

sudo npm cache clean --force
