为什么我得到这个错误?
您的编译器配置已经配置了一个转储后自动加载脚本，即IlluminateFoundationComposerScripts::postAutoloadDump，它与您在命令行上使用的PHP版本不兼容(并且composer运行)。
该Composer脚本与它自己的laravel/laravel/composer.json配置相结合，质量很低，并且在可操作使用之前没有检查其需求。因此，您会看到一长串PHP错误消息(诊断消息)，这些消息可能会令人惊讶地嘈杂，因此您无法发现这个PHP版本不匹配的明显问题。
满足编写器的要求。Json配置，然后就可以了。如果你是laravel/laravel的用户，也许你应该在上游报告这个问题，似乎它可以从一些用户的反馈中受益。
