Just installed Lumen and got NotFoundHttpException
<p>I'm searching for a solution ... it's getting so frustrating.
After a fresh installation of Lumen by Laravel, I simply can't access the "/" route. When I try to, it throws an error:</p>

<pre><code>NotFoundHttpException in RoutesRequests.php line 443:

in RoutesRequests.php line 443
at Application-&gt;handleDispatcherResponse(array('0')) in RoutesRequests.php line 380
at Application-&gt;Laravel\Lumen\Concerns\{closure}() in RoutesRequests.php line 629
at Application-&gt;sendThroughPipeline(array(), object(Closure)) in RoutesRequests.php line 382
at Application-&gt;dispatch(null) in RoutesRequests.php line 327
at Application-&gt;run() in index.php line 28
</code></pre>
