Laravel 5 Class Collective Html HtmlServiceProvider not found on AWS

I'm aware that there are several other questions with the same error, such as: Class 'IlluminateHtmlHtmlServiceProvider' not found. 5th Laravel

My issue is that I followed all of the suggested steps to resolve this on my local (XAMPP), and it worked flawlessly. The problem arose when I attempted to deploy to my AWS Ubuntu box (nginx). I followed all of the standard procedures: http://laravelcollective.com/docs/5.1/html#installation

When I did a git pull from what I had pushed from my local, my providers and aliases were added. Perhaps this file should have been gitignored and the change made on the server manually?

Next, add your new provider to the providers array of config/app.php:

  'providers' => [
    // ...
    Collective\Html\HtmlServiceProvider::class,
    // ...
  ],

Finally, add two class aliases to the aliases array of config/app.php:

  'aliases' => [
    // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
    // ...
  ],

I then manually added:

Begin by installing this package through Composer. Edit your project's composer.json file to require laravelcollective/html.

"require": {
    "laravelcollective/html": "5.1.*"
}

And finally, I ran:

composer.phar update

It was running this command that throws the error:

PHP Warning:  Module 'mcrypt' already loaded in Unknown on line 0

PHP Fatal error:  Class 'Collective\Html\HtmlServiceProvider' not found in /usr/share/nginx/html/cbt/vendor/compiled.php on line 6

Script php artisan clear-compiled handling the pre-update-cmd event returned with an error

I then tried running php artisan clear-compiled, to see if that would do anything, and got:

PHP Warning:  Module 'mcrypt' already loaded in Unknown on line 0
PHP Fatal error:  Class 'Collective\Html\HtmlServiceProvider' not found in /usr/share/nginx/html/cbt/vendor/compiled.php on line 6716

I know my Nginx ubuntu environment is not the same as a windows xampp env, but I'm still unsure why following the Laravel-provided instructions for adding this doesn't seem to work. Would greatly appreciate some advice on this.
