title: Heroku local [WARN] No ENV file found when using Config library to manage environments
body: <p>I'm using <a href="https://www.npmjs.com/package/config" rel="nofollow noreferrer"><code>Config</code></a> library to mange my environments, so i do not have <code>.env</code> file, how to make heroku ignore this fact ?. </p>
  
  <p>It work fine when i deploy to Heroku, but fails locally.
  I tried:</p>
  
  <p><code>heroku local web</code> which fires <code>npm run build &amp;&amp; node dist/Server</code> // <code>[WARN] No ENV file found</code></p>
