    if ($this->app->environment('local', 'testing')) {
        $this->app->register(DuskServiceProvider::class);
    }
}

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",

    "laravel/dusk": "^2.0"
  },

The Exception is :

If you're experiencing this problem while in a developing environment and accidentally landed here due to the title, you should check that your .env file is set up for development. It should contain the line

APP_ENV=local

Here is an example of how the .env file could look: https://github.com/laravel/laravel/blob/master/.env.example

And here is the Laravel documentation: https://laravel.com/docs/5.7/configuration

Also, in composer.json, laravel/dusk should be listed under require-dev and not require.

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:

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!
