Nachdem ich composer update in meinem Laravel 9-Projekt ausgeführt habe, ist die folgende Fehlermeldung aufgetreten:
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.

Es scheint, dass das Update abgeschlossen wurde, aber etwas ist schief gelaufen und jetzt wird in der Konsole syntax 错误，意外标记“)” Finder.php 上的错误：588 angezeigt.
Ich habe die Datei überprüft und sie sieht korrekt aus.
Wenn ich das Projekt im Browser öffne, erhalte ich diese Fehlermeldung:

Ich habe außerdem alle Caches im bootstrap/cahce/ 和 storage/framework/cache/data/、storage/framework/sessions/、storage/framework/views/-Ordner geleert.
Ich verwende PHP Version 8.0.16.
Composer-Version 2.0.12 2021-04-01 10:14:59.
Irgendeine Idee, wie man dieses Problem lösen kann?

要继续使用 php 8.0，请将这些条目添加到您的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.*", ... }为我使用 php 8.0 和 Laravel 9。
我找到了一个解决方案：
docker pullcomposer以升级最新版本的composer（从2.0到2.2）composer update
