Error: Cannot find module, despite NODE_PATH being set

[janstrohbeck]

Description

I use Typescript with a basePath setting, so that I can require my files from an absolute base path:

import navigation from 'redux/interfaces/navigation'

This gets transpiled to:

const _navigation = require('redux/interfaces/navigator')

The redux folder is in ./src/internal, so I have to set NODE_PATH accordingly.

I want to use iron-node to debug my mocha unit test, which I can execute like this:

NODE_PATH=./src/internal node node_modules/mocha/bin/_mocha --opts mocha.opts 'tests/**/*.spec.ts' 'tests/**/*.spec.tsx'

This works, but if I replace node with iron-node, it cannot find the files in ./src/internal (see error log below)

Steps to Reproduce

I reproduced the issue with the following 2-file setup:

1. Create file src/internal/redux/interfaces/navigation.js:

 module.exports = {
    a: true
}

2. Create file test/test.js:

const _navigation = require('redux/interfaces/navigation')
console.log(_navigation.a)

3. Execute in shell (runs without errors): NODE_PATH=./src/internal node test/test.js
4. Execute in shell (fails with module not found): NODE_PATH=./src/internal iron-node test/test.js

Expected behavior: [What you expect to happen]

iron-node should run without errors and find the required file.

Actual behavior: [What actually happens]

iron-node does not find the required file.

Reproduces how often: [What percentage of the time does it reproduce?]

Always.
