[BUG] dist-tag in package.json not re-evaluated

[SchulteDev]

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

Context

I am using a packages npm-dist-tag in my package.json

// An example
"devDependencies": {
  "nx": "canary"
}

Running npm i after adding such a dependency to the package.json works as intended, for time being 19.2.0-canary.20240528-7f11a1d of nx is being fetched and written to the package-lock.json.

dist-tag not re-evaluated

Now, I am using a npm-dist-tag, which does not exist:

"devDependencies": {
  "nx": "dist-tag-not-available-oohhhhhh"
}

Running npm i after adding such a dependency does not work - which is in my opinion correct:

$ npm i
npm error code ETARGET
npm error notarget No matching version found for nx@dist-tag-not-available-oohhhhhh.
npm error notarget In most cases you or one of your dependencies are requesting
npm error notarget a package version that doesn't exist.

But, if I first install nx=canary as I described in context, and change canary to dist-tag-not-available-oohhhhhh in the package.json afterwards, npm i just works fine. The package-lock.json remains untouched in this case, with nx still pointing to 19.2.0-canary.20240528-7f11a1d

Additional question

I wonder, what happens when nx=canary is being used, and the canary dist-tag gets updated - does npm i update the actual version of nx?

Expected Behavior

In the second case, when a npm-dist-tag in the packge.json is being changed to a non-existing one, I would expect NPM to throw an error as it does, when I try to init such a dependency.

Steps To Reproduce

1. Add nx=canary as dependency to package.json
2. npm i (nx is being installed)
3. Change nx to nx=dist-tag-not-available-oohhhhhh in package.json
4. npm i => executes just fine, nx=canary remains, no error

Environment

npm: 10.8.0
Node.js: v20.10.0
OS Name: Windows 11
System Model Name: Lenovo IdeaPad

This behavior would be very useful, and I believe the most expected. Similarly, I was looking forward to conveniently reference a context of possibly changing code without having to constantly update the version number. Analogous to how DNS works for IP addresses.

@SchulteMarkus U mentioned an issue that dist-tag in package.json not re-evaluated. i have gone through all the steps which u mentioned above but there is not change in changing the dependencies and we are not getting any error based on ur environment. so it is not an issue

That's in my opinion a surprising behaviour, a misbehaviour.

@SchulteMarkus Please upgrade the npm and node to the latest version and try again.
