将 php 从 5.6 升级到 7.4 后，项目 symfony 2.8 中 AppKernel.php 的问题

编程问答 2022-05-22

问题描述

最近几天我尝试逐步升级我的项目。我有 Symfony 2.8，composer 2。最近我找到了用于升级的 rector/rector 包，但是当我尝试安装它时出现了冲突。接下来我尝试安装 rector/rector-prefixed。它也给安装带来了很多问题，但经过研究，我已经将我的 php 版本更新到 7.4 并且运行良好。我已经进行了 Composer 更新和安装，但同时出现了新错误。使用 AppKernel。在一切都很好之前，该应用程序运行良好。现在我在浏览器中收到消息：Composer 在您的平台中检测到问题：“您的 Composer 依赖项需要 PHP 版本 >= 7.4.0”。“

在每个命令（例如：php app/console list）之后的控制台中，现在我收到此消息：

#!/usr/bin/env php
PHP Fatal error:  Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "TixiCoreDomainBundle" from namespace "Tixi\CoreDomainBundle".

这是我在 AppKernel.php 中的内容：

public function registerBundles(): array
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),new Symfony\Bundle\SecurityBundle\SecurityBundle(),new Symfony\Bundle\TwigBundle\TwigBundle(),new Symfony\Bundle\MonologBundle\MonologBundle(),new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),new Tixi\CoreDomainBundle\TixiCoreDomainBundle(),new Tixi\ApiBundle\TixiApiBundle(),new Tixi\SecurityBundle\TixiSecurityBundle(),new Tixi\App\AppBundle\TixiAppBundle(),new FOS\RestBundle\FOSRestBundle(),new FOS\OAuthServerBundle\FOSOAuthServerBundle(),new JMS\SerializerBundle\JMSSerializerBundle(),new APY\BreadcrumbTrailBundle\APYBreadcrumbTrailBundle(),new Knp\Bundle\SnappyBundle\KnpSnappyBundle(),new Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),);

        if (in_array($this->getEnvironment(),array('dev','test'),true)) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

我尝试编写 use 语句，但它没有改变任何内容。 我的 composer.json：

{
  "name": "symfony/framework-standard-edition","license": "MIT","type": "project","description": "The \"Symfony Standard Edition\" distribution","autoload": {

  }
}

有人知道如何解决这个问题吗？

是的，该类存在。问题是每 4 个具有名称空间的类都以 Tixi 开头。这个类是空的，它们扩展了 Symfony 的 Bundle 类。他们是这样的：

<?php

namespace Tixi\ApiBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

/**
 * Class TixiApiBundle
 * @package Tixi\ApiBundle
 */
class TixiApiBundle extends Bundle
{
}

这些类的位置与它们的命名空间一起传递。

在为自动加载更改 composer.json 中的命名空间后，我遇到了另一个错误，这次是从 composer.json 运行脚本。这是错误消息：

解决方法

自动加载器配置不正确：

  "autoload": {
    "psr-4": {
      "Tixi\\": "src/"
    },"classmap": [ "app/AppKernel.php","app/AppCache.php" ]
  },

这告诉自动加载器搜索 Tixi 中 src 命名空间中的所有类。据此，类 Tixi\CoreDomainBundle\TixiCoreDomainBundle 应该位于 src/CoreDomainBundle/TixiCoreDomainBundle.php，但它位于 src/Tixi/CoreDomainBundle/TixiCoreDomainBundle.php。

将 Tixi 子文件夹中的所有内容向上移动一级，或者调整您的类加载器设置 - 将其更改为 src/Tixi/ 可能会有所帮助
