After updating to Laravel 5.8, when running php artisan dusk, I get:

Symfony\Component\Debug\Exception\FatalThrowableError : Argument 1 passed to Dotenv\Dotenv::__construct() must be an instance of Dotenv\Loader, string given, called in /vendor/laravel/dusk/src/Console/DuskCommand.php on line 208

The issue is that Dusk 5.0 wants to support both Laravel 5.7 and 5.8, but they require different versions of the vlucas/phpdotenv package (^2.2 vs. ^3.3).

[yannisc]

phpdotenv 3.3 came with Laravel 5.8. Should I downgrade to 2.2?

[staudenmeir]

Composer won't let you do that and it would break Laravel.

I don't think there's anything you can do right now. This has to be fixed by Dusk.

[yannisc]

I think the same. Thanks for your help!

[driesvints]

Released v5.0.1 which should fix this.

[yannisc]

Thanks, @driesvints! That fixed the problem!
