作曲家更新后出错：

php artisan clear-compiled 使用包信息加载作曲家存储库 更新依赖项（包括 require-dev） 您的需求无法解析为一组可安装的软件包。

Answer 1

您的composer.json 文件引用了以下依赖项：

"illuminate/database": "5.0.*"
"illuminate/events": "5.0.*"

但是，您需要的 Laravel 框架版本是 5.1.*。

只需如下更改Illumination版本依赖即可：

"illuminate/database": "5.1.*"
"illuminate/events": "5.1.*"

不过，它们实际上是核心 Laravel 框架的一部分，因此您不需要将它们显式声明为依赖项。

我已经对此进行了测试，并且可以正常工作。

一个单独的问题是您定义了一个引用“数据库”的类映射，它实际上并没有解决任何问题。但这是一个单独的问题。
