What could be causing npm to not recognize my module in the "require" statement?

Currently, I am in the process of developing an npm module and conducting tests before making it available to the public. The method I am following is outlined in a blog post found at this link. However, I am encountering difficulties when trying to require even a basic module. Below is my package.json file:

{
  "name": "mystuff",
  "version": "0.0.1",
  "description": "",
  "main": "./lib/index",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "MIT"
}

Additionally, here is the very simple index.js file that I am working with:

'use strict'

exports.test_call = function() {
  return "Hello Module"
}

My expectation was that I could simply require my module, but unfortunately, this has not been successful:

> require('mystuff')
Error: Cannot find module 'mystuff'
    at Function.Module._resolveFilename (module.js:327:15)
    at Function.Module._load (module.js:278:25)
    at Module.require (module.js:355:17)
    at require (internal/module.js:13:17)
    at repl:1:1
    at REPLServer.defaultEval (repl.js:252:27)
    at bound (domain.js:281:14)
    at REPLServer.runBound [as eval] (domain.js:294:12)
    at REPLServer.<anonymous> (repl.js:417:12)
    at emitOne (events.js:83:20)

Despite the unsuccessful attempt to require the module, it seems that the installation location is correct, and the module functions as intended when required from its specific directory:

> require('./node_modules/mystuff')
{ test_call: [Function] }
> require('./node_modules/mystuff').test_call()

I am puzzled by why I cannot require the module directly. What could be the missing piece of this puzzle?

Answer №1

Since updating node and npm to versions v9.3.0 and v5.5.1, the problem has been resolved.
