我的 Zend Framework 项目中有一些使用自定义视图助手的自定义表单元素。它们被加载并在开发机器上正常工作，但是当我将项目移动到我的 EC2 服务器时，它们没有被加载。
来自 application.ini：
resources.view.helperPath.Custom_View_Helper_ = APPLICATION_PATH "/../library/Custom/View/Helper/"
服务器返回的错误：
Warning: Exception caught by form: Plugin by name 'Multiselect' was not found in the registry;

什么可能导致它在我的开发机器上工作但在 EC2 上不工作？
