Are you trying to upgrade the composer command itself, or upgrade the dependencies of the current project? — Quezler

Seems like one of the packages required laravel 5.2 i guess but your installation used 5.4.*. To be exact this package "barryvdh/laravel-cors" — Norlihazmey Ghazali

"require": {
    "php": ">=5.6.4",
    "guzzlehttp/guzzle": "~6.0",
    "laravel/framework": "5.4.*",
    "laravel/tinker": "~1.0",
    "barryvdh/laravel-cors": "0.8.1",
    "webpatser/laravel-uuid": "2.*",
    "intervention/image": "~2.1"
},

I found a solution for this issue. I just removed "barryvdh/laravel-cors":"0.8.0" from composer.json, because Laravel 5.4 doesn't support barryvdh/laravel-cors. So after removing that line I run composer update and it works.
