Answer 1

"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"
},

我找到了解决此问题的方法。 我只是删除"barryvdh/laravel-cors":"0.8.0"从composer.json ，因为Laravel 5.4不支持barryvdh/laravel-cors 。 因此，删除该行后，我运行composer update并成功运行。
