Lumen php artisan config:cache not found
<p>I'm trying out the PHP micro Framework Lumen (from laravel).
When I  set up Lumen and I try to use the <code>php artisan config:cache</code> command like in Laravel, I get this error :</p>

<blockquote>
  <p>[InvalidArgumentException]<br>
    There are no commands defined in the "config" namespace.</p>
</blockquote>

<p>So I have problem when I try to deploy the files to server, so I have to change <code>.env</code> file to change the database username and password.</p>

<p>This makes me think <code>config</code> is not available in artisan </p>

<p>How can I add it to artisan ? </p>
