What steps will reproduce the bug?

1: cd to directory another than $HOME
2: Just install module, do npm link $module in home folder, check, that folder is created or linked.
3: try to run require('module')

How often does it reproduce? Is there a required condition?

sometimes yes, sometimes not, (now ALWAYS)

What is the expected behavior?

That require will work, when ~/node_modules contains module with exact name and package.json with all the needed stuff

What do you see instead?

require('mail-confirm')
Uncaught Error: Cannot find module 'mail-confirm'
Require stack:

• at Module._resolveFilename (node:internal/modules/cjs/loader:955:15) at Module._load (node:internal/modules/cjs/loader:803:27) at Module.require (node:internal/modules/cjs/loader:1021:19) at require (node:internal/modules/cjs/helpers:103:18) { code: 'MODULE_NOT_FOUND', requireStack: [ '' ]

}

Additional information

some modules worked, some not, but now nothing

I've converted this to a discussion because this seems like a misunderstanding of how npm and the module loader work, not a bug in node.

The module loader is described in node's documentation, npm's docs you can find here: https://docs.npmjs.com/

I actually have the same problem. You import a file from a lib/ folder and within that module it is unable to import 'pg'
