[BUG] npm version throws TypeError on 'trim'.

[Johannestegner]

Current Behavior:

When executing npm version {version} or even npm version from-git in my CI pipeline I get the following error:

0 verbose cli [ '/usr/local/bin/node', '/usr/local/bin/npm', 'version', 'from-git' ]

Expected Behavior:

The npm package version should be updated to defined version.

Steps To Reproduce:

I use the following docker image (which is built from my ci as well): https://github.com/orgs/jitesoft/packages/container/package/node

The following package is the latest I tried to build: https://github.com/jitesoft/eslint-config

Environment:

OS: Alpine linux
Node: 15.0.1
NPM: 7.0.3

Can you try on npm v7.0.7?

[Johannestegner]

Will do!

Edit: Takes a couple of more minutes, want to use the same image to be sure it's the same environment :P

Alright, finally got it up and running with the correct version of npm. Still the same issue though.
I find it odd that I experience this, due to the fact that I'm quite sure that thousands of people do this every day, and I don't use any odd commands really.

If you can't reproduce it, let me know and I'll set up a small reproducible case for you! :)

[Johannestegner]

Easiest way to test it is:

docker run --rm -i -t ghcr.io/jitesoft/node:latest /bin/ash

git clone https://github.com/jitesoft/eslint-config.git
cd eslint-config/
npm version 1.2.3

Node is built from source and if you wish to see the build procedure it can be found here:

https://github.com/jitesoft/docker-node-base/blob/master/.gitlab-ci.yml#L115

Just let me know if you need any more info or anything else.

Just updated my windows host npm and tested another package, it gave the same issue.

[Johannestegner]

I must say that this a huge issue, as I have about 20 packages which are deployed quite often (weekly auto, and more often manually), each of which uses the same CI pipeline, and without the availability of the version command, they are all broken.
I guess I could change the base pipeline to use sed or similar to change the version, but one would expect the command to work as intended :/

I reproduced locally on Mac with your repo. I noticed the package.json in your example repository does not have a version field. Adding one eliminates the error, so that may be a potential work-around.

The package.json documentation says:

If you plan to publish your package, the most important things in your package.json are the name and version fields as they will be required.

Ah tyvm @shadowspawn, that will be easy to fix! :)

Going to handle it over on libnpmversion. Thanks for the report! npm/libnpmversion#4
