[BUG] `npm update` generates package-lock.json that isn't considered in-sync by `npm ci`

[ulrichstark]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

Take this package.json:

{
    "private": true,
    "name": "repro-app",
    "version": "1.0.0",
    "license": "UNLICENSED",
    "type": "module",
    "dependencies": {
        "@tanstack/react-start": "1.133.2",
        "@tanstack/nitro-v2-vite-plugin": "1.132.40"
    }
}

Running npm update and then npm ci shows following error:

npm error code EUSAGE
npm error
npm error `npm ci` can only install packages when your package.json and package-lock.json or npm-shrinkwrap.json are in sync. Please update your lock file with `npm install` before continuing.

Expected Behavior

Running npm update should produce a lock file that is considered "in sync" by npm ci

Steps To Reproduce

1. Clone https://github.com/ulrichstark/unstable-npm-lock-file-repro.git
2. Run npm update
3. Run npm ci

I guess this is a duplicate of #8669

I'm not sure. My issue is also present in 11.6.0 while your linked issue seems to have appeared first in 11.6.2.

[ulrichstark]

Also #6787 sounds similar, but is about npm install and not about npm update

I also mentioned on #8669 that I had a similar issue at least in 11.6.1 not sure if it was also in 11.6.0 but the outcome looks very familiar
