Maatwebsite Excel安装报错：MemoryCache与PsrExt\SimpleCache兼容问题

问题现象 #

该项目在本地及两台服务器上运行正常，但在某一台服务器安装时触发致命错误：

PHP Fatal error:  Declaration of Maatwebsite\Excel\Cache\MemoryCache::get(string $key, mixed $default = null): mixed must be compatible with PsrExt\SimpleCache\CacheInterface::get($key, $default = <default>) in /var/www/html/livepartners_v3.com/vendor/maatwebsite/excel/src/Cache/MemoryCache.php on line 62

• 手动指定安装"psr/simple-cache": "2.0"可解决该问题，但其他10台设备自动安装"psr/simple-cache": "3.0"却能正常运行
• 执行composer update --no-script可暂时恢复运行，但后续执行dump-autoload时仍会触发相同错误

接口与实现方法签名对比 #

对比Psr\SimpleCache\CacheInterface的get方法与MemoryCache的实现，两者签名完全一致：

Psr\SimpleCache\CacheInterface::get #

<?php

namespace Psr\SimpleCache;

interface CacheInterface
{
    /**
     * Fetches a value from the cache.
     *
     * @param string $key     The unique key of this item in the cache.
     * @param mixed  $default Default value to return if the key does not exist.
     *
     * @return mixed The value of the item from the cache, or $default in case of cache miss.
     *
     * @throws \Psr\SimpleCache\InvalidArgumentException
     *   MUST be thrown if the $key string is not a legal value.
     */
    public function get(string $key, mixed $default = null): mixed;

Maatwebsite\Excel\Cache\MemoryCache::get #

namespace Maatwebsite\Excel\Cache;

use Psr\SimpleCache\CacheInterface;

class MemoryCache implements CacheInterface
{
    public function get(string $key, mixed $default = null): mixed
    {
        if ($this->has($key)) {
            return $this->cache[$key];
        }

        return $default;
    }
}

已尝试的排查操作 #

• 更新PHP至8.1.21版本
• 升级Composer到最新版本
• 清理Composer缓存、删除vendor目录后重新安装依赖
• 测试不同PHP版本（均为8.1分支）

核心疑问 #

为何仅该服务器会解析出无类型声明的PsrExt\SimpleCache\CacheInterface::get方法，其他服务器均无此问题？
