Laravel: Declaration of App\Providers\EventServiceProvider::boot

Question

I'm currently updating to Laravel 5.4 and have encountered the following error in the console.

Declaration of App\Providers\EventServiceProvider::boot(Illuminate\Contract
s\Events\Dispatcher $events) should be compatible with Illuminate\Foundatio
n\Support\Providers\EventServiceProvider::boot()

Here is my composer.json

{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {
    "php": ">=5.5.9",

    "illuminate/html": "5.0.*",
    "laravelcollective/html": "^5.4.0"
},
"require-dev": {

    ],

    ],
    "pre-update-cmd": [

    ],
    "post-update-cmd": [

    ]
},

    "preferred-install": "dist"
}
}

Are you following the Upgrade Guide here: laravel.com/docs/5.4/upgrade ? The Laravel docs generally outline the upgrade steps pretty well. Also, from what version of Laravel are you upgrading from? — kjones

You're updating to 5.4, so some things are going to change.

The boot method no longer requires an argument passed to it, nor does the parent:

Remove the argument completely from both the function, and the parent::boot() so no arguments are passed to either:

public function boot() 
{
    parent::boot();
}
