"Packaging" breaks the expected behavior of 'npm install <folder>'

[thoughtsunificator]

Environment

• OS Version: Linux
• Node.js Version: v23.1.0

Actual behavior

Error: Cannot find module '/tmp/fast-glob-test/node_modules/fast-glob/build/index.js'

Expected behavior

The module should load as expected.

Steps to reproduce

• Clone fast-glob repo
• Inside a directory, test, init a new npm package (npm init -y)
• npm install ../fast-glob
• node -e "const fg = require('fast-glob');"

Code sample

const fg = require('fast-glob');

The npm install command only installs dependencies. The package is written in TypeScript and requires compilation. If you clone a repository rather than installing a package from the npm registry, you need to understand its internal arrangements (assembly, bundling, etc.).

The set of commands should be as follows:

npm i
npm run build
npm run bundle

Except there is no bundling or assembling phase specified by the package manager, being npm in this case. npm install is expected to work as is.
