[BUG] npm version from-git removes prerelease stanzas

[aendra-rininsland]

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

If I have a git tag like v2.1.0-alpha.1 and I run npm version from-git --no-git-tag-version, it rewrites the tag's version to v2.1.0 and puts that into package.json's version property.

Expected Behavior

The prerelease stanza of the Git tag should be preserved when running npm version from-git. The current behaviour unexpectedly removes it. This led to a not-at-all-fun experience this morning due to inadvertently publishing a prerelease version as a stable version.

At the very least, this behaviour should be documented.

Steps To Reproduce

1. git tag v1.0.0-alpha.1
2. npm version from-git --no-git-tag-version
3. The version property of package.json will now read 1.0.0

Environment

• npm: 11.3.0
• Node.js: 22.15.0
• OS Name: circleci/node@5.2.0
• System Model Name: CircleCI
• npm config:

; node bin location = /usr/local/bin/node
; node version = v22.15.0
; npm local prefix = /home/circleci/project
; npm version = 11.3.0
; cwd = /home/circleci/project
; HOME = /home/circleci
; Run `npm config ls -l` to show all defaults.
