我在 Laravel 5.8 中有項(xiàng)目。我想更新到6.0。如何將我的項(xiàng)目更新到版本 6？我的作曲家.json：{    "name": "laravel/laravel",    "type": "project",    "description": "The Laravel Framework.",    "keywords": [        "framework",        "laravel"    ],    "license": "MIT",    "require": {        "php": "^7.2",        "bensampo/laravel-enum": "^1.26",        "caouecs/laravel-lang": "~4.0",        "evilnet/dotpay": "^2.1",        "fideloper/proxy": "^4.0",        "geocoder-php/google-maps-provider": "^4.4",        "geocoder-php/nominatim-provider": "^5.1",        "intervention/image": "^2.4",        "jenssegers/agent": "^2.6",        "laravel/framework": "6.*",        "laravel/tinker": "^1.0",        "mews/captcha": "^2.2",        "php-http/guzzle6-adapter": "^2.0",        "php-http/message": "^1.7",        "spatie/laravel-cookie-consent": "^2.6",        "toin0u/geocoder-laravel": "^4.1",        "torann/laravel-meta-tags": "^3.0",        "unisharp/laravel-ckeditor": "^4.7",        "unisharp/laravel-filemanager": "dev-master"    },    "require-dev": {        "barryvdh/laravel-debugbar": "^3.2",        "beyondcode/laravel-dump-server": "^1.0",        "filp/whoops": "^2.0",        "fzaninotto/faker": "^1.4",        "mockery/mockery": "^1.0",        "nunomaduro/collision": "^2.0",        "phpunit/phpunit": "^7.5"    },    "config": {        "optimize-autoloader": true,        "preferred-install": "dist",        "sort-packages": true    },    "repositories": {        "packagist.org": {            "type": "composer",            "url": "https://packagist.org"        }    },    "extra": {        "laravel": {            "dont-discover": []        }    },    "autoload": {        "psr-4": {            "App\\": "app/"        },        "classmap": [            "database/seeds",            "database/factories"        ],我該如何修復(fù)它？在我的項(xiàng)目中可以這樣做嗎？我的文件 Composer.json 是否正確？有可能更新嗎？
