I've just read this:

All Together...
https://nodejs.org/docs/latest/api/modules.html#modules_all_together

From this document, if a script in /Uesrs/foo (Y) does require('/b.js'); (X), it should be resolved to /Users/foo/b.js (Y + X). But as long as I tested, it's resolved to an absolute path (/b.js).

I guess either the document or implementation is wrong.

Here is the code.
