Missing module.parent in Docker container

[DenisCarriere]

The strangest thing happened, everything works in Node 6 & 7, however whenever I bring conf into any of the latest Docker container (ex: node:6) it crashes.

https://github.com/sindresorhus/conf/blob/master/index.js#L13

Error on require

# node
> const Conf = require('conf')
TypeError: Path must be a string. Received null

Module parent does not exist

> module.parent
undefined
> module
Module {
  id: '<repl>',
  exports: {},
  parent: undefined,
  filename: null,
  loaded: false,
  children: [],
  paths:
   [ '/usr/src/app/repl/node_modules',
     '/usr/src/app/node_modules',
     '/usr/src/node_modules',
     '/usr/node_modules',
     '/node_modules',
     '/root/.node_modules',
     '/root/.node_libraries',
     '/usr/local/lib/node' ] }
