Packages not installing, class does not exist error, Laravel 5.2
<p>The package is an email registration functionality. Here is my composer.json file</p>

<pre><code>  "require": {
    "php": "&gt;=5.5.9",
    "laravel/framework": "5.2.*",
    "cviebrock/eloquent-sluggable": "^3.1",
    "jrean/laravel-user-verification": "^2.0"
},
</code></pre>

<p>The trouble package is the user-verification one at the bottom. </p>

<p>Here are my providers in app.php</p>

<pre><code>'providers' =&gt; [

    /*
     * Laravel Framework Service Providers...
     */
    Illuminate\Auth\AuthServiceProvider::class,
    Illuminate\Broadcasting\BroadcastServiceProvider::class,
