Packages with dir as "main" in package.json do not resolve.

When trying to import a package that has a directory as its “main” field, there will be an error

example/example2.js:3: ERROR - Failed to load module "abc"
import abc from 'abc'
^
1 error(s), 0 warning(s)

node_modules
|-abc
  |-build
    -- index.js
  --package.json

cat package.json

{"name":"abc", "main":"build"}

@zavr-1 It’s going to be a bit before I can get to this. Webpack4 support is currently taking all my time.
