Laravel 9 composer syntax error, unexpected token ")"-CodePudding

After in my Laravel 9 project I run composer update I faced this error message:

Writing lock file
Installing dependencies from lock file (including require-dev)

  - Downloading fruitcake/laravel-cors (v3.0.0)

Generating optimized autoload files

> @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

It seems update was finished, but something went wrong and now in the console I get syntax error, unexpected token ")" error on Finder.php:588.

I checked this file and it's looks correct.

When I open my project in browser I get this error:

I cleared all the caches in bootstrap/cahce/ and in storage/framework/cache/data/, storage/framework/sessions/, storage/framework/views/ folders too.

I use PHP version 8.0.16.

Composer version 2.0.12 2021-04-01 10:14:59.

Any idea how can I fix this?

CodePudding user response：

I did :

composer require --ignore-platform-reqs symfony/finder 6.1

and i have a similar issue now :

So i think it's the version of symfony/finder that is not compatible with php 8.0, try to downgrade any symfony related package to 6.0.x, because i don't think you require symfony/finder directly, but some other package like symfony/http-client

I think you perhaps installed dependencies using php 8.1 at some point and you got wrong packages versions, or perhaps you have laravel 10 installed and not laravel 9 ?
