可能原因及解决方案 #

1. 检查配置文件中的别名与服务提供者 #

打开config/app.php：

• 确认providers数组已正确添加Yajra\Oci8\Oci8ServiceProvider::class
• 检查aliases数组，确保没有错误的小写'auth'别名，正确的Auth别名应为'Auth' => Illuminate\Support\Facades\Auth::class,，若存在错误别名，直接删除或修正

2. 清除Laravel缓存 #

执行以下命令清除所有缓存文件，避免旧配置残留：

php artisan config:clear
php artisan route:clear
php artisan cache:clear
php artisan view:clear

3. 验证版本兼容性 #

确认Yajra OCI8版本与当前Laravel版本匹配：

• Laravel 8 → yajra/laravel-oci8 ^8.0
• Laravel 9 → ^9.0
• Laravel 10 → ^10.0
  查看composer.json中的版本声明，不兼容则修改后执行composer update重新安装适配版本

4. 排查服务提供者代码 #

若自定义过服务提供者，或修改过Yajra OCI8的相关代码，检查是否有错误调用auth类的逻辑，应使用Auth:: facade或完整命名空间Illuminate\Auth\AuthManager来引用认证类
