Laravel5.8项目Composer1执行install提示psr/simple-cache未安装求助

我在Laravel 5.8版本的项目中必须使用Composer 1版本。执行composer install命令时，在InstalledVersions.php第159行出现如下错误：

Package psr/simple-cache is not installed

但psr/simple-cache实际已经存在于vendor目录中，我已删除vendor目录并尝试重新安装，问题仍未解决。该如何修复？

项目的composer.json配置如下：

• 清理Composer缓存
  执行命令清除缓存，避免旧缓存数据导致的识别问题：

  composer clear-cache
  

• 明确指定psr/simple-cache版本
  在composer.json的require节点中添加psr/simple-cache的兼容版本约束（Laravel 5.8适配^1.0版本）：

  "require": {
      // 其他依赖保持不变
      "psr/simple-cache": "^1.0"
  }
  

  修改后重新执行composer install

• 重置依赖文件
  删除composer.lock和vendor目录，重新安装依赖：

  rm composer.lock
  rm -rf vendor
  composer install
  

• 临时关闭自动加载优化
  修改composer.json的config部分，将optimize-autoloader设为false：

  "config": {
      "optimize-autoloader": false,
      "preferred-install": "dist",
      "sort-packages": true
  }
  

  安装完成后可以再改回true

• 排查PHP环境
  确保PHP 7.3版本的扩展没有冲突，尤其是和缓存相关的扩展（如redis、mongodb）是否正常加载
