[BUG] <`npm` is case-sensitive towards the drive letter in Windows 10 causing module name errors when using `npm run dev` in a NextJS project in the eshell tool within emacs>

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 am an emacs user attempting to use eshell to use npm run dev in a NextJS project. I've configured the project from scratch as per the next docs, and this is the output:

Expected Behavior

The expected behavior should be that the server runs with no errors or warnings given that the project was setup exactly as the next docs instruct. I will note that if you delete node_modules and use the driveup tool in M-x shell instead of eshell, re-install the next dependencies and run npm run dev, it works as expected, so the lowercase drive letter is the issue.

Steps To Reproduce

1. Install emacs as a scoop app:

scoop bucket add extras
scoop install emacs

3. Run emacs -Q in PowerShell (do not use an init file, run as default emacs)
4. Run M-x eshell and cd into an empty directory to configure the project
5. Run npm i next react react-dom
6. Edit the package.json with M-x find-file to add:

"scripts": {
  "dev": "next dev"
},

7. Run npm run dev
8. See error.

Environment

• npm: 8.1.0
• Node.js: 16.13.0
• OS Name: Windows 10 Pro
• System Model Name: Dell Precision 5760
• npm config:

; "builtin" config from c:\Program Files\nodejs\node_modules\npm\npmrc

prefix = "C:\\Users\\me\\AppData\\Roaming\\npm"

; "user" config from C:\Users\me\.npmrc

//registry.npmjs.org/:_authToken = (protected)

; node bin location = c:\Program Files\nodejs\node.exe
; cwd = c:\Users\me\pandora\test-bug
; HOME = C:\Users\me
; Run `npm config ls -l` to show all defaults.

Start by reproducing the report's Windows 10 setup with Emacs eshell, npm i next react react-dom, and npm run dev, comparing the lowercase and uppercase drive-letter paths. Then trace npm's handling of those paths; no source file or test is named in the report. Done means the Next.js development server runs without module-name errors in the stated setup.
