composer update laravel/framework

发现相同的问题。打开composer.lock并检查“laravel/framework”的所有依赖项，然后逐个删除文件夹并再次使用composer update。这对我很有效。

• 确保在composer.json中更改laravel的版本
• 删除所有供应商文件夹
• 编写器更新吗

如果失败，请在此处再次发布您的回复

它只是说laravel不使用特定版本的whoops。

laravel需要Mcrypt PHP扩展

在您的机器上安装Mcrypt扩展。这只是composer的愚蠢行为。人们怎么能帮助您呢？您只需责怪composer，而没有提供

composer.json

？composer一直都是在一个我尝试DL laravel的例子中，我遇到了ng。这完全让我不使用框架。我以为composer是用C编写的，但后来看到github repo它是用PHP编写的，难怪它挂起了。他们需要真正修复它。
