【问题描述】：

我在 Laravel 的 composer.json 文件中收到以下错误...

错误：第 10 行的解析错误： ...l": "~2016.04", , "require-dev"

----------^

期待“字符串”

composer.json

    ,

        ]
    ,
    "scripts": 
        "post-root-package-install": [
            "php -r \"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": [
        "php artisan vendor:publish --tag=public --force",
            "php artisan vendor:publish",
            "php artisan migrate",
            "Illuminate\\Foundation\\ComposerScripts::postUpdate",
            "php artisan optimize"
        ]

【参考方案1】：

您应该删除最后一行的 , 并更好地练习使用 CMD 命令 这对您来说很容易。当您使用 cmd 时，它总是下载最新版本，并且 composer.json

中没有错误

composer require aimeos/aimeos-laravel

【参考方案2】：

请不要在最后一个对象的末尾使用“，”，它告诉作曲家在此之后还有另一个字符串，作曲家没有找到任何其他字符串。所以你会遇到这种类型的错误...

删除那个逗号和愉快的编码..

【参考方案3】：

JSON 对象或数组中不能有尾随逗号，您需要从以下行中删除它们

"aimeos/aimeos-laravel": "~2016.04",

"symfony/dom-crawler": "2.8.*|3.0.*",

【参考方案4】：

您应该删除每个数组末尾的最后一个逗号。
