If you use an older Version of mySQL or MariaDB Laravel throws an error on the first migration on your database. Thats cause the defaultStringLentth needs to be set to a maximum length of 191 characters.

    public function boot()
    {
        Schema::defaultStringLength(191);
    }
}

Add this to your AppServiceProvider.php File and rerun your migration

Dont forget to add

use Illuminate\Support\Facades\Schema;
