Can't require npm package

Question

I'm building a npm package that I want to publish. I followed this instructions and works untill I get to the require part. I've installed the package with npm install . -g and I can see it listed when I do npm ls -g. But when I require it I get

var VuePrint = require('vue-print')
Error: Cannot find module 'vue-print'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Module.require (module.js:353:17)
    at require (internal/module.js:12:17)
    at repl:1:16
    at REPLServer.defaultEval (repl.js:252:27)
    at bound (domain.js:287:14)
    at REPLServer.runBound [as eval] (domain.js:300:12)
    at REPLServer.<anonymous> (repl.js:417:12)
    at emitOne (events.js:82:20)

Thats the error from node-repl, but I got the same in different environment with different stacktrace. So, How can I require my package to publish it later? Here are the relevant parts of my package.json file in case it helps

You've installed the package globally, but not locally by the looks of things. `require` doesn't check the folder where global modules are installed. As the docs say, if you `npm install ../my-package` then it will be installed into the node_modules folder and you should be able to use `require` — dan, Apr 13 '16 at 16:11
I can require any other globally installed package. Also, I've tried before with the package locally installed — Yerko Palma, Apr 13 '16 at 16:59
Assuming [this](https://www.npmjs.com/package/vue-print) is your module it works for me using `npm install vue-print`. The module should be in your `node_modules` folder though. See http://stackoverflow.com/questions/15636367/nodejs-require-a-global-module-package regarding using `require` on global modules. — dan, Apr 13 '16 at 17:30
yes, that is, the install is working fine, but when requiring it it can't find it — Yerko Palma, Apr 13 '16 at 17:31
Does it work if you install it locally rather than globally? — dan, Apr 13 '16 at 17:32
no, it works if I directly require the source file `require('./src/vueprint.js')`. But when I require the module from the `npm install` (globally or locally) it doesn't work. I think that I have some misunderstanding about the config on my package.json, I guess that it should take the file that I added in the `main` option, but I tried with the source and compiled files (I'm using browserify) with no success — Yerko Palma, Apr 13 '16 at 17:36

You don't need to install you package as a global package (-g). Just go to your project folder (where you want use vue-print) and run command "npm i vue-print", after that you can use require('vue-print') in this folder

That require the packaged to be published. I didn't mention it but I already publish the package and it was successfully published, but again, not required. Globally or locally it makes no difference – Yerko Palma Apr 13 '16 at 17:13
