Framework: Project fails in production because fzaninotto/faker is missing

[sebastiaanluca]

• Laravel Version: 5.4.25
• PHP Version: 7.1
• Database Driver & Version: MySQL 5.7

Description:

No idea why I haven't noticed this before, but my project's production error logs contain lots of lines of the following exception:

staging.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Class 'Faker\Factory' not found in /home/project/vendor/laravel/framework/src/Illuminate/Database/DatabaseServiceProvider.php:78

DatabaseServiceProvider clearly requires the faker package, while it's only installed as dev package (and even optional to include in any project).

$this->app->singleton(FakerGenerator::class, function ($app) {
    return FakerFactory::create($app['config']->get('app.faker_locale', 'en_US'));
});

Was investigating why the beanstalkd daemons on production stopped executing jobs and what's causing timeouts when trying to access the site. Not sure if related though.

Steps To Reproduce:

In composer.json:

"require-dev": {
    "fzaninotto/faker": "^1.6"
},

Deploy to production (which only installs everything under require, excluding dev packages and thus faker too).

Hi,
Same error with Laravel 5.4.27.

Can't deploy with "composer install --no-dev" because no artisan's commands will work.

Faker should only be used in development, looks like you use faker somewhere in your code in production, that causes the container to create an instance of FakerGenerator for you and thus call the closure.

Make sure you're not using faker anywhere in your production code, and if you must, just move faker to the require section.

Themsaid, that's in the core.

[crynobone]

The piece of code only register the service to the container. Until a code ask to resolve FakerGenerator you shouldn't have this issue. So @themsaid comment is correct. Somewhere in your code (or packages) that you load attempt to resolve which is not possible .

Effectively I found a line that make EloquentFactory, that needs FakerFactory ...

Removed this line permits to move "fzaninotto/faker" in composer "require" section.

This is also happening in Laravel 5.6

In DatabaseServiceProvider.php line 78:

         Class 'Faker\Factory' not found

If you have installed package nwidart/laravel-modules and run composer install --no-dev make sure your .env config APP_ENV= is set to production otherwise you'll encounter this issue if it's set to local. Hope that helps someone

the @wmandai did not work for me. Why is it now required ?
