在我的 Laravel 9 專案中執行 composer update 後，我遇到了以下錯誤訊息：
Writing lock file Installing dependencies from lock file (including require-dev) Package operations: 0 installs, 1 update, 1 removal - Downloading fruitcake/laravel-cors (v3.0.0) - Removing asm89/stack-cors (v2.1.1) - Upgrading fruitcake/laravel-cors (v2.2.0 => v3.0.0): Extracting archive 77 package suggestions were added by new dependencies, use `composer suggest` to see details. Generating optimized autoload files > Illuminate\Foundation\ComposerScripts::postAutoloadDump > @php artisan package:discover --ansi In Finder.php line 588: syntax error, unexpected token ")" Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1
似乎更新已完成，但出了點問題，現在在控制台中我收到 syntax 錯誤，意外標記“)” Finder.php 上的錯誤：588。
我檢查了這個文件，它看起來是正確的。
當我在瀏覽器中開啟專案時，出現此錯誤：

我也清除了bootstrap/cahce/ 和storage/framework/cache/data/、storage/framework/sessions/、storage /framework/views/ 資料夾中的所有快取。
我使用 PHP 版本 8.0.16。
Composer 版本 2.0.12 2021-04-01 10:14:59。
知道如何解決這個問題嗎？
要繼續使用 php 8.0，請將這些項目新增到您的composer.json
"require": { ... "symfony/console": "6.0.*", "symfony/error-handler": "6.0.*", "symfony/finder": "6.0.*", "symfony/http-foundation": "6.0.*", "symfony/http-kernel": "6.0.*", "symfony/mailer": "6.0.*", "symfony/mime": "6.0.*", "symfony/process": "6.0.*", "symfony/routing": "6.0.*", "symfony/var-dumper": "6.0.*", "symfony/event-dispatcher": "6.0.*", "symfony/string": "6.0.*", "symfony/translation": "6.0.*", "symfony/translation-contracts": "3.0.*", "symfony/service-contracts": "3.0.*", "symfony/event-dispatcher-contracts": "3.0.*", "symfony/deprecation-contracts": "3.0.*", ... }為我使用 php 8.0 和 Laravel 9。
我找到了一個解決方案：
docker pullcomposer以升級最新版本的composer（從2.0到2.2）composer update
