我是 Zend2 的新手，我正在关注 Zend 上的专辑教程。我收到以下错误：
Fatal error: Uncaught Error: Class 'ArrayUtils' not found in E:\Temp\htdocs\zf-tutorial\public\index.php:43 Stack trace: #0 {main} thrown in E:\Temp\htdocs\zf-tutorial\public\index.php on line 43
我找不到什么问题，我做错了什么？我错过了一些代码吗？还是我错过了教程中的一些规则？这是我的 index.php 文件
<?php
use Zend\Mvc\Application;
/**
* Display all errors when APPLICATION_ENV is development.
*/
if ($_SERVER['APPLICATION_ENV'] === 'development') {
error_reporting(E_ALL);
ini_set("display_errors", 1);
}
/**
* This makes our life easier when dealing with paths. Everything is relative
* to the application root now.
*/
chdir(dirname(__DIR__));
// Decline static file requests back to the PHP built-in webserver
if (php_sapi_name() === 'cli-server') {
$path = realpath(__DIR__ . parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH));
if (__FILE__ !== $path && is_file($path)) {
return false;
}
unset($path);
}
// Composer autoloading
include __DIR__ . '/../vendor/autoload.php';
if (! class_exists(Application::class)) {
throw new RuntimeException(
"Unable to load application.\n"

}
// Retrieve configuration
$appConfig = require __DIR__ . '/../config/application.config.php';
if (file_exists(__DIR__ . '/../config/development.config.php')) {
$appConfig = ArrayUtils::merge($appConfig, require __DIR__ . '/../config/development.config.php');
}
// Run the application!
Application::init($appConfig)->run();
