php - Laravel 7 从 Laravel 6 升级时抛出错误 255

Question

我只是尝试将 Laravel 从 v6 升级到 v7，我的 php 版本是 7.3，我升级了 Laravel 站点上所述的所有依赖项，并删除了冲突的包，升级似乎已完成，但出现以下错误:

Generating optimized autoload files> Illuminate\Foundation\ComposerScripts::postAutoloadDump

我已经尝试删除供应商文件夹并再次安装，也使用composer dump autoload，并尝试清除laravel缓存，但总是得到相同的错误。

在您的 app/Exceptions/Handler.php 文件:替换 Exception带有 Throwable 的类型提示类型提示。

如 Upgrade guide 中所述.
