【问题描述】：

所以，我正在尝试创建一个新项目，但内核发生了一些事情，我不太了解。 每次我生成新的 Bundle 并尝试创建控制器或任何东西时，都会出现此错误：

php 致命错误：未捕获 Symfony\Component\Debug\Exception\ClassNotFoundException：试图 从命名空间“ContactBoxBundle”加载类“ContactBoxBundle”。做过 您忘记了另一个名称空间的“使用”语句？在 /var/www/ContactBox/app/AppKernel.php:19 堆栈跟踪：

我以前在 Symfony 上做过项目，但从来没有发生在我身上。有任何想法吗？我使用控制台命令“bin/console generate:bundle”生成了 Bundle。它生成了它应该生成的所有内容，包括默认控制器、模板和类，但由于这个错误，我无法进一步对此做任何事情。有什么想法吗？

AppKernel.php

<?php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel

    public function registerBundles()
    
        $bundles = [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),

            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new AppBundle\AppBundle(),
            new ContactBoxBundle\ContactBoxBundle(),
        ];

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

            if ('dev' === $this->getEnvironment()) 
                $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
                $bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
            
        

        return $bundles;
    

    public function getRootDir()
    
        return __DIR__;
    

    public function getCacheDir()
    
        return dirname(__DIR__).'/var/cache/'.$this->getEnvironment();
    

    public function getLogDir()
    
        return dirname(__DIR__).'/var/logs';
    

    public function registerContainerConfiguration(LoaderInterface $loader)
    
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');

请帮忙，我正因此而发疯！

【问题讨论】：

奇怪地类似于：***.com/questions/44908210/…同一作者和所有内容。

我已经回答了两个我不知道是否正确，我还没有看到最古老的问题@Cerad

【参考方案1】：

尝试从这里更改您的 composer.json 文件：

"psr-4": 
    "AppBundle\\": "src/AppBundle"
 

到这里：

"psr-4": 
    "": "src/"
,

这样你就加载了src下的所有Bundle。

像这样：

"psr-4": 
    "AppBundle\\": "src/AppBundle",
    "ContactBoxBundle\\": "src/ContactBoxBundle",

或者您可以根据需要指定要加载的每个 Bundle。

之后你需要从控制台制作：

composer dump-autoload
