即使是最新版本的gloudemans/shoppingcart 也不兼容 Laravel v6 或 v7，但 v1.4 中的tcg/voyager 至少需要 Laravel v6。

您应该寻找该购物车包的替代品，或者在与 Laravel v5 兼容的旧版本中安装 Voyager。比如v1.3是兼容的，可以使用安装

composer require tcg/voyager "^1.3"

【讨论】：

我用这个：并解决了：“tcg/voyager”：“1.5.2.*”

【解决方案2】：

我面临同样的问题，让我们试试这个，

步骤 1. 重新启动系统

第 2 步。运行composer global require laravel/installer

第 3 步。使用创建新的 laravel 项目 composer create-project --prefer-dist laravel/laravel blog

避免使用laravel new blog

步骤 4. 将终端路径更改为项目文件夹并运行 composer require tcg/voyager

接下来关注voyager docs
