Question

I upgrated my project from laravel 5.4 to laravel 5.5 ,

I dont have any problem in local env but in server i get this exception ,

I searched a lot and i know this issue may be duplicated but no solutions solved my problem!

How can i not registering dusk when environment is production?

i wrote this code in AppServiceProvider.php :

public function register()
{
    // Dusk, if env is appropriate
    if ($this->app->environment('local', 'testing')) {
        $this->app->register(DuskServiceProvider::class);
    }
}

but it seems not working. can anyone help?

EDITED : my composer.json file:

 "require-dev": {
    "filp/whoops": "~2.0",
    "fzaninotto/faker": "~1.4",
    "mockery/mockery": "1.*",
    "phpunit/phpunit": "^7.0.3",
    "symfony/css-selector": "4.0.*",
    "symfony/dom-crawler": "4.0.0",
    "barryvdh/laravel-ide-helper": "^2.4",
    "laravel/dusk": "^2.0"
  },

The Exception is :

Exception
It is unsafe to run Dusk in production.

Answer 1

In Laravel 5.5, packages are automatically discovered and loaded so you will probably need to tell it not to load dusk.

One way is to add this to your composer.json

"extra": {
    "laravel": {
        "dont-discover": [
            "laravel/dusk"
        ]
    }
},

Also, you can add it to your dev dependencies and when you deploy in production, use:

composer install --no-dev

Taylor wrote an article about it here.

Look, it does not work because it is configured to work on local and testing environment. I guess that you need to add 'production' (if your production is called 'production in your .env file environment:

AppServiceProvider

public function register()
{
    // Dusk, if env is appropriate
    if ($this->app->environment('local', 'testing', 'production')) {
        $this->app->register(DuskServiceProvider::class);
    }
}

When installing to production server I just needed to use the --no-dev flag

composer install --no-dev

Good luck!
