Laravel迁移报错：无法声明CreateUsersTable类，提示名称已占用

执行php artisan migrate时触发如下致命错误：

PS C:\Users\joshu\laraveljobs_app> php artisan migrate

   INFO  Running migrations.

PHP Fatal error:  Cannot declare class CreateUsersTable, because the name is already in use in C:\Users\joshu\laraveljobs_app\database\migrations\create_users_table.php on line 7

用户已通过findstr /s "CreateUsersTable"命令排查，仅找到一处类声明，但错误依旧。

排查及解决方法 #

• 检查文件名大小写冲突：Windows系统路径不区分大小写，若database/migrations目录下存在create_users_table.php和CreateUsersTable.php（仅大小写不同），PHP会加载两次导致类重复，手动检查目录内文件。
• 清理类加载缓存：执行以下命令清除Laravel缓存的类加载信息：

  php artisan clear-compiled
  php artisan optimize:clear
  

• 扩大搜索范围排查类声明：使用忽略大小写的搜索命令，覆盖更多可能的声明场景：

  findstr /s /i "class CreateUsersTable" *.php
  

• 检查文件重复加载逻辑：确认create_users_table.php是否被其他文件通过require/include重复引入，或存在自定义迁移加载规则导致文件重复加载。
• 刷新Composer自动加载：执行composer dump-autoload刷新自动加载规则，避免因配置问题导致迁移文件被重复扫描。
