[BUG] devDependencies considered for minimum version despite --omit-dev

[Sainan]

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

When running npm i --omit=dev in a project with devDependencies requiring newer versions of Node/NPM, e.g. @typescript/native-preview the install will fail on older Node versions despite the fact that this is completely irrelevant to the elected package tree.

Expected Behavior

Minimum version is computed without dev dependencies -> install succeeds.

Steps To Reproduce

1. When using Node <20.6.0
2. In a project where devDependencies contains e.g. "@typescript/native-preview": "7.0.0-dev.20250523.1"
3. Run npm i --omit=dev
