[BUG] ERESOLVE - peer dependency conflicts by packages which should get replaced

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

I have the following package.json structure:

{
  "name": "reproduction",
  "private": true,
  "version": "0.0.0",
  "type": "module",
  "scripts": {},
  "devDependencies": {
    "@storybook/react-vite": "8.4.7",
    "@storybook/test": "8.4.7",
    "storybook": "8.4.7"
  }
}

Running npm install correctly installs all packages. I want to update now manually the packages to their latest version 8.5.1.

When I run npm install, I get the following error message:

npm error code ERESOLVE
npm error ERESOLVE could not resolve
npm error
npm error While resolving: reproduction@0.0.0
npm error Found: @storybook/react-vite@8.4.7

I would appreciate any help. We have been debugging this for a long time, and we already cleaned up our peer-dependencies and transitive peer-dependencies so that they are correctly declared. But currently, we don't know how to continue. npm is also the only package manager that fails.

Expected Behavior

npm install doesn't fail after package update

Steps To Reproduce

1. Create a project with the following package.json

{
  "name": "reproduction",
  "private": true,
  "version": "0.0.0",
  "type": "module",
  "scripts": {},
  "devDependencies": {
    "@storybook/react-vite": "8.4.7",
    "@storybook/test": "8.4.7",
    "storybook": "8.4.7"
  }
}

2. npm install
3. Update manually the packages to their latest version 8.5.1:

{
  "name": "reproduction",
  "private": true,
  "version": "0.0.0",
  "type": "module",
  "scripts": {},
  "devDependencies": {
    "@storybook/react-vite": "8.5.1",
    "@storybook/test": "8.5.1",
    "storybook": "8.5.1"
  }
}

4. npm install

Above error appears

Context:
"@storybook/test@8.5.1" has a peer dependency on storybook@^8.5.1
"@storybook/react-vite@8.5.1" has a peer dependency on storybook@^8.5.1 and @storybook/test@8.5.1

Environment

• npm: 10.9.0
• Node.js: 22.12.0
• OS Name: macOS Sonoma 14.4.1
• System Model Name: Macbook Pro
• npm config:

; "user" config from /Users/valentinpalkovic/.npmrc

//registry.npmjs.org/:_authToken = (protected)
//registry.yarnpkg.com/:_authToken = (protected)
registry = "https://registry.yarnpkg.com"

; node bin location = /Users/valentinpalkovic/.nvm/versions/node/v22.12.0/bin/node
; node version = v22.12.0
; npm local prefix = /Users/valentinpalkovic/Projects/vitejs-vite-izegxbtn
; npm version = 10.9.0
; cwd = /Users/valentinpalkovic/Projects/vitejs-vite-izegxbtn
; HOME = /Users/valentinpalkovic
; Run `npm config ls -l` to show all defaults.

Reproduce the failure with the two package.json versions and npm 10.9.0 on Node.js 22.12.0, then inspect npm's peer-dependency resolution and ERESOLVE handling. Done means updating all three Storybook packages to 8.5.1 and running npm install without the reported dependency conflict.
