我试图安装gloudemans/购物车，但遇到错误：
Installation failed, reverting
Problem 1
- Installation request for gloudemans/shoppingcart ^2.6 -> satisfiable by gloudemans/shoppingcart[2.6.0].
- Conclusion: remove laravel/framework v7.17.2
- Conclusion: don't install laravel/framework v7.17.2
- gloudemans/shoppingcart 2.6.0 requires illuminate/events 5.1.*
我还尝试安装不同版本的 laravel，illuminate/events像必需的一样，但仍然没有，总是有相同的问题。
作曲家需要格鲁德曼斯/购物车：

对于 Laravel 5.7 或更高版本，购物车包不再起作用。这是一个分叉，其工作方式完全相同，但支持较新版本的 Laravel：
https://packagist.org/packages/hardevine/shoppingcart
根据您的composer.json您没有安装illuminate/events. 所以你可以安装illuminate/events，然后安装gloudemans/shoppingcart.它会起作用。安装时，请使用composer require illuminate/events，然后作曲家需要gloudemans/shoppingcart
