npm run dev fails silently when using npm — playground package.json uses "my-module": "latest" instead of "file:.."

[Phenix333]

Description

When scaffolding a new Nuxt module with npm create nuxt -- -t module my-module and using npm (not pnpm),
the playground cannot resolve the local module, causing the plugin to never be injected and myModule
to be ignored in nuxt.config.ts — with no error in the console.

Root cause

The generated playground/package.json has:

"dependencies": {
  "my-module": "latest"
}

Steps to reproduce

1. npm create nuxt -- -t module my-module
2. cd my-module
3. npm run dev
4. Plugin from src/runtime/plugin.ts is never injected — no error shown

Fix

Change playground/package.json to use "file:..":

"dependencies": {
  "my-module": "file:.."
}

Environment

• npm: 11.10.0
• nuxt: 4.3.1
• @nuxt/module-builder: 1.0.2
• OS: Windows 11
