title: if I try bunyan.createLogger my application doesn't start and doesn't show error
body: <p>If I try to use winston module I have sucess. Nevertheless, if I try to use bunyan my application doesn't start neither show any error (or I don't know how to find the error).</p>
  
  <p>I am debugging using Visual Studio Code although I don't think it is relevant to this question.</p>
  
  <p>If I just require winston, I get no error. The issue happens when add "bunyan.createLogger({name: "myapp"})" as showed bellow.</p>
  
  <p>I am not interested to compare bunyan with winston. I am defenitely interested to use bunyan unless there is a reason like conflict with other modules (I mean other require showed bellow). I just mentioned winston here because I can use it successfully and I noted that winston doesn't depend on ".createLogger" (at least the examples I have read never use ".createLogger" for winston and always show it for bunyan).</p>
  
  <p>Something called my attention although I don't know if it is related to this case neither I know the why: I always install the dependencies using npm install "the dependency" -s because I want to keep a track of all modules used in my project in package.json. A bit strange to me that I don't see it after npm installed (see my package.json bellow).</p>
  
  <pre><code>var express = require('express');
  var bodyParser = require('body-parser');
  var Client = require('node-rest-client').Client;
  var bunyan = require('bunyan');
  //var winston = require('winston');
  
  var logBunyan = bunyan.createLogger({name: "myapp"});
  
  //winston.log('info', 'Hello distributed log files!');
  //winston.info('Hello again distributed logs');
  </code></pre>
  
  <p>...</p>
  
  <p>package.json (Shouldn't winston and bunyan appears here since both were installed with "- save"?) </p>
