It depends on Node image version :

• no error: 4.*
• Error: Cannot find module 'semver' : >4

Same thing with offical Node images.

This is an NPM issue : https://github.com/npm/npm/issues/16807, https://github.com/npm/npm/issues/15558, https://github.com/nodejs/docker-node/issues/449

Simple workaround is to use latest Node image with latest NPM and not update NPM manually.

Are you sure you have semver in your package.json?

This is what worked for me for the update-npm step in config.yml:

yarn global add npm@latest

This is what worked for me for the update-npm step in config.yml:

yarn global add npm@latest

I have used your command but npm version is not latest, I added this step in circle to verify. - run: name: Check npm and node version command: | node --version npm --version

The output was 5.5.1. Currently the latest version is 6.4.1.
