Using Node's require to resolve file path does not resolve correct library from node_modules

[nkbt]

This issue is quite tricky to even report and I understand if you just close it as "cannot reproduce". I even thought about not opening this issue as it is quite hard to explain. But it may be somewhat helpful for others, so I will do my best to explain the problem.

The issue is in this function requireCssFile
https://github.com/michalkvasnicak/babel-plugin-css-modules-transform/blob/master/src/index.js#L52-L72

I've added to the start of it

console.log(require.resolve.paths('@myscope/my-lib/Styles.css'))
process.exit(1)

And I am getting this

[
  '/Users/nkbt/test/node_modules/babel-plugin-css-modules-transform/build/node_modules',
  '/Users/nkbt/test/node_modules/babel-plugin-css-modules-transform/node_modules',
  '/Users/nkbt/test/node_modules',
  '/Users/nkbt/node_modules',
...
]

That seems like a correct list of paths to look for libs, but the real problem is that I am doing build within nested subfolder which has it's own node_modules inside

console.log(`process.cwd()`, process.cwd())

> process.cwd() /Users/nkbt/test/.pk/services/my-service/docker/app

This is what I would expect instead (check with just node, not going through the build loop)

$ node
> process.cwd()
'/Users/nkbt/test/.pk/services/my-service/docker/app'
> require.resolve.paths('@myscope/my-lib/Styles.css')
[
  '/Users/nkbt/test/.pk/services/my-service/docker/app/repl/node_modules',
  '/Users/nkbt/test/.pk/services/my-service/docker/app/node_modules',
  '/Users/nkbt/test/.pk/services/my-service/docker/node_modules',
  '/Users/nkbt/test/.pk/services/my-service/node_modules',
  '/Users/nkbt/test/.pk/services/node_modules',
  '/Users/nkbt/test/.pk/node_modules',
  '/Users/nkbt/test/node_modules',
  ...
]

I do not know too much about writing babel transforms, but I assume it may provide some context similar to cwd() from where files/libs need to be searched

I did not check but very much certain same problem would happen if I am to use global installation of babel/babel-plugin-css-modules-transform, because it would resolve to a babel-plugin-css-modules-transform folder in node directory and not the app one.

For the moment my only solution would be to not import css from a package directly, but update package so it exports css, because if paths are relative, this transform works ok.
