npm ERR! cb() never called in windows10

 

I had the same problems and lost hours trying to solve it :(.

But then i found out that my firm has installed some new kind of firewall with self signed certificate.

Quick solution was:

npm config set strict-ssl=false

After that everything started working without 'npm cb() never called' errors

node.js - npm ERR! cb() never called in windows10 - Stack Overflow
