NPM Install error : npm ERR! cb() never called!

What I Wanted to Do

npm install to complete without errors

What Happened Instead

The process stopped giving the error “npm ERR! cb() never called!”, creating a log file in the process. err-cb.log (236.1 KB)

Reproduction Steps

The environment I currently have, would be difficult to reproduce since it is a large application.


I’ve tried the following:

Platform Info

$ npm --versions
{ ‘material2-srcs’: ‘7.0.0-beta.0’,
npm: ‘5.6.0’,
ares: ‘1.10.1-DEV’,
cldr: ‘32.0’,
http_parser: ‘2.7.0’,
icu: ‘60.1’,
modules: ‘57’,
nghttp2: ‘1.25.0’,
node: ‘8.10.0’,
openssl: ‘1.0.2n’,
tz: ‘2017c’,
unicode: ‘10.0’,
uv: ‘1.19.1’,
v8: ‘6.2.414.50’,
zlib: ‘1.2.11’ }

$ node -p process.platform


I would like to find out why this is happening, resolve the issue such that I can begin to add new packages.

Any help or guidance supplied would be most gratefully received.

Anyone with even a suggestion as to what to try next? Any help will be gratefully received.

  1. Were there were any Unhandled rejections (they don’t show up in the error log)? Those could point to different problems.
  2. Try npm v6.6.0-next.0.
