尝试将Laravel从版本6升级到版本7时出现问题

问题描述

您好，Wonderfull所有人，

我们在尝试将Laravel从版本6升级到7时遇到问题。这是错误消息：

Script php artisan optimize handling the post-update-cmd event returned with error code 255

composer.json如下：

{
"name": "laravel/laravel","description": "The Laravel Framework.","keywords": [
    "framework","laravel"
],"license": "MIT","type": "project","require": {
    "php": "^7.1","laravel/framework": "7.*","venturecraft/revisionable": "1.*","barryvdh/laravel-dompdf": "^0.8.3","doctrine/dbal": "^2.5","guzzlehttp/guzzle": "^6.2","maatwebsite/excel": "^3.1","laravel/passport": "^7.0.0","nesbot/carbon": "^2.39","kylekatarnls/laravel-carbon-2": "^1.0.0"
},"require-dev": {

},"autoload": {

        "database"
    ],"psr-4": {
        "App\\": "app/"
    }
},"autoload-dev": {
    "classmap": [
        "tests/TestCase.php"
    ]
},"scripts": {
    "post-root-package-install": [
        "php -r \"file_exists('.env') || copy('.env.example','.env');\""
    ],"post-create-project-cmd": [
        "php artisan key:generate"
    ],"post-install-cmd": [
        "Illuminate\\Foundation\\ComposerScripts::postInstall","php artisan optimize"
    ],"post-update-cmd": [
        "Illuminate\\Foundation\\ComposerScripts::postUpdate","php artisan optimize"
    ]
},"config": {
    "preferred-install": "dist"
}

} 有人知道该怎么做吗？

亲切的问候，
