Laravel - can't install from my source control - php

Question

I need to automate my laravel project setup/upgrade on my production machine from source control.
I wrote a bash script to clone the source from the GIT repo and run the setup.
The git code is going to the folder /var/www/prod/mainapp/, so the following bash code is running after the git command:
cd /var/www/prod/mainapp/app/
composer install # composer update will not work as well
php artisan dump-autoload
php artisan optimize
I am getting the following error when the code reaches to: php artisan optimize
PHP Fatal error: Class 'App\Providers\SocialUserProvider' not found in /var/www/prod/mainapp/app/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146
in my app.php i have the following providers:
App\Providers\FacebookGraphProvider::class,
Torann\GeoIP\GeoIPServiceProvider::class,
App\Providers\SocialUserProvider::class,
this is my composer.json:
{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {

},

]
},
"config": {

}
}

Answer 1

You need to add to the classmap the line that will tell who should be autoloaded. app/Providers
"classmap": [
"database",
"app/Facades",
"app/Services",
"app/Providers" //this is the missing part.
]

Answer 2

I've come across this a few times.
My workaround is to run
composer install --no-scripts
You are getting that error due to the pre install scripts in your composer.json file and by adding that flag to the install process you skip these scripts.
Once you have everything installed you can then just use composer install and composer update as you usually would.
