Laravel 5.2: While moving to production, class "Collective\Html\HtmlServiceProvider" not found in vendor folder

I have been trying to move my laravel app to production. I following below steps

1. git clone
2. composer install
3. set env variables
4. (artisan key:generate)
5. artisan migrate --seed

But when i ran composer install, am getting the following error

Class 'Collective\Html\HtmlServiceProvider' not found in vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146

I know this error means, laravelcollective not added in composer.json and need to following steps as mentioned here.

But i already have done the same thing in dev mode and now the composer.json has require "laravelcollective" and aliases in config/app.php.

My question is, do i need to the same thing what i have done in dev (resolving laravelcollective issue) for every new production instance that i am gonna set it up ?
