Laravel RuntimeException无法扫描"数据库"中的类,这些类似乎不是文件,也不是文件夹

Question

我正在尝试运行命令

composer update 

收到此错误消息:

[RuntimeException]无法扫描"数据库"中的类,这些类似乎不是文件,也不是文件夹

这是我的代码composer.json:

    ]
},

我们可以通过database在项目根目录下创建文件夹来解决此问题<PROJECT_ROOT>/database。如果我们要确保所有东西都可以使用，可以删除composer.lock文件并再次运行composer update命令。
