php 从 5.6 升级到 7.4 后项目 symfony 2.8 中 AppKernel.php 的问题
Problem with AppKernel.php in project symfony 2.8 after upgrade php from 5.6 to 7.4
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 rector/rector 升级包，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，并且一切顺利。我已经更新并安装了作曲家，但同时出现了新错误。与应用内核。之前一切都很好，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”。“
并且在每个命令之后的控制台中（例如：php app/console 列表）现在我收到这条消息：
#!/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(),

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，但没有任何改变。

有人知道如何解决这个问题吗？

是的，class 存在。问题是每 4 个 class 的命名空间都以 Tixi 开头。这个 class 是空的，它们扩展了 Symfony 的 Bundle class。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
{
}
并且这个 classes 的位置通过它们的命名空间。
编辑：18.03
更改 composer.json 中的命名空间以进行自动加载后，我遇到了另一个错误，这次是来自 composer.json 的 运行 个脚本。这是错误消息：

自动加载器配置不正确：
"autoload": {
"psr-4": {
"Tixi\": "src/"
},
"classmap": [ "app/AppKernel.php", "app/AppCache.php" ]
},
这告诉自动加载器在 src 的 Tixi 命名空间中搜索所有 classes。据此，class Tixi\CoreDomainBundle\TixiCoreDomainBundle 应位于 src/CoreDomainBundle/TixiCoreDomainBundle.php，但它位于 src/Tixi/CoreDomainBundle/TixiCoreDomainBundle.php。
要么将 Tixi 子文件夹中的所有内容向上移动一级，要么调整您的 class 加载程序设置 - 将其更改为 src/Tixi/ 可能会有所帮助
