Question

我是Laravel Framework的新手，我正在尝试从Github克隆一个项目后安装一个Laravel项目。我按照this post中提到的所有步骤进行了操作，但无法安装项目。

每次都在“作曲家安装”步骤中卡住了。我得到以下错误，这与我做“composer update”时的错误相同：

$ composer update

我不知道它做了什么但是根据其他帖子的一些建议，我还尝试了“composer update”和“composer update”，然后是“composer dumpautoload”。我不知道它有什么问题，但似乎没有什么工作。我到处搜索了几个小时但找不到任何解决方案。任何人，请帮忙。

这是我的composer.json文件：

    ]

}

Answer 1

从services.json文件夹中删除bootstrap/cache文件，然后运行

composer dump-autoload -o

Laravel 5.3项目安装：脚本php artisan优化处理返回的post-update-cmd事件，错误代码为255
