laravel - 尝试安装 gloudemans/shoppingcart，安装失败，将 ./composer.json 还原为其原始内容？
问题描述
我尝试安装 gloudemans/shoppingcart 时遇到错误：
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 并且illuminate/events需要，但仍然没有，总是遇到同样的问题。
