What steps will reproduce the bug?

https://github.com/JounQin/test/tree/repro/node_require_resolve_paths

Simply run node test.js

On node 10:

`resolve` npm package: <CWD>/fixtures/bar.js
`require.resolve` built-in function: <CWD>/fixtures/bar.js

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

Persist

What is the expected behavior? Why is that the expected behavior?

There is a related old issue #29139.

What do you see instead?

On node 12+, of course including Node LTS (20+)

`resolve` npm package: /Users/JounQin/Workspaces/GitHub/test/fixtures/bar.js
node:internal/modules/cjs/loader:1404
  throw err;
  ^

Error: Cannot find module 'bar'

}

Additional information

I believe there is no reports because most projects use http://npmjs.com/resolve instead, and it behaviors same as Node 10-, and I'm trying to remove resolve as dependency, so I just met this issue at https://github.com/un-ts/eslint-plugin-import-x/pull/272#issuecomment-2915145320

リンクされた再現コードの test.js を Node 10 と Node 12+ で実行し、paths を指定した場合の require.resolve の結果を比較します。スタックトレースに示された CommonJS ローダーのパスと、関連する issue #29139 を読みます。再現コードが外部パッケージ resolve なしで一貫して fixtures/bar.js を解決できれば完了です。
