Description

I use require.resolve(request, { paths }) to find a file to load relative to a different directory, however this stopped working in node@12, where require.resolve throws Error: Cannot find module ....

Expected Behavior

The require.resolve call returns the absolute path to the requested file, according to the submitted path(s).

Actual Behavior

In node@12, an error is raised.

Steps to reproduce:

/// index.js
const path = require('path');
try {
  const filePath = require.resolve('./target', {
    paths: [path.resolve(__dirname, 'directory')]
  });
  console.log(`Found: ${filePath}`);
} catch (e) {
  console.error('Failed!');
}

/// directory/target.js
console.log('Reached there!');

Result

$ node -v
v12.1.0
$ node index.js
Failed!

$ /usr/local/opt/node@10/bin/node -v
v10.15.3
$ /usr/local/opt/node@10/bin/node index.js
Found: /tmp/repro/directory/target.js

$ /usr/local/opt/node@8/bin/node -v
v8.16.0
$ /usr/local/opt/node@8/bin/node index.js
Found: /tmp/repro/directory/target.js

I believe this is already fixed by #27598, which should be available in the upcoming node v12.3.0.

I just verified locally that this is fixed on master, and the fix will go out in 12.3.0 as previously mentioned. I'm going to close this issue out.
