None npm package error getaddrinfo on test locally

Hi all I have my own npm package where I want to make some updates and before publish I would like to test locally.

But when I try to launch my script I get this error:

{ RequestError: getaddrinfo ENOTFOUND function function:80
    at ClientRequest.req.once.err (/Users/someUser/Sites/package-info/node_modules/got/index.js:73:21)

  code: 'ENOTFOUND',
  message: 'getaddrinfo ENOTFOUND function function:80',
  host: 'function',
  hostname: 'function',
  method: 'HEAD',
  path: '%20(scope)%20%7B%0A%09var%20rc%20=%20require(%27rc%27)(%27npm%27,%20%7Bregistry:%20%27https://registry.npmjs.org/%27%7D);%0A%09var%20url%20=%20rc[scope%20+%20%27:registry%27]%20%7C%7C%20rc.registry;%0A%09return%20url.slice(-1)%20===%20%27/%27%20?%20url%20:%20url%20+%20%27/%27;%0A%7Dpackage-info' }

This is my index.js

'use strict';
var got = require('got');
var registryUrl = require('registry-url');
var Promise = require('pinkie-promise');

module.exports = function (name) {
    if (typeof name !== 'string') {
        return Promise.reject(new Error('package name required'));
    }

    return got.head(registryUrl + name.toLowerCase())
        .then(function (res) {
            return {
                'test': 'test'
            };
        })
        .catch(function (err) {
            if (err.statusCode === 404) {
                err.message = 'Package doesn\'t exist';
            }

            throw err;
        });
};

And this is my cli.js

#!/usr/bin/env node
'use strict';
var pkg = require('./package.json');
var info = require('./');
var argv = process.argv.slice(2);
var input = argv[0];

function help() {
    console.log(pkg.description);
    console.log('');
    console.log('Usage');
    console.log('  $ package-info <package-name>');
    console.log('');
    console.log('Example');
    console.log('  $ package-info pageres');
}

if (!input || argv.indexOf('--help') !== -1) {
    help();
    return;
}

if (process.argv.indexOf('-v') !== -1 || process.argv.indexOf('--version') !== -1) {
    console.log(pkg.version);
    return;
}

info(input)
.then(version => console.log(version))
.catch(err => {
  console.error(err);
  process.exit(1);
});

To launch locally my package I use from command line terminal:

my-package-name another-package-name

How to solve this error?
