【问题描述】：
您好，当我尝试加载我的 symfony 2 应用程序时，会出现这个问题，
AppKernel.php 第 25 行中的 ClassNotFoundException：尝试从命名空间“Sonata\DoctrineORMAdminBundle”加载类“SonataDoctrineORMAdminBundle”。 您是否忘记了另一个命名空间的“使用”语句？
这是我的 AppKernel.php 文件，
<?php
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;
class AppKernel extends Kernel
{
public function registerBundles()
{
$bundles = array(
new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
new Symfony\Bundle\SecurityBundle\SecurityBundle(),
new Symfony\Bundle\TwigBundle\TwigBundle(),
new Symfony\Bundle\MonologBundle\MonologBundle(),
new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
new Symfony\Bundle\AsseticBundle\AsseticBundle(),
new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
new AppBundle\AppBundle(),
new kcc\AdminBundle\kccAdminBundle(),
new JMS\SerializerBundle\JMSSerializerBundle(),
new Sonata\CoreBundle\SonataCoreBundle(),
new Sonata\BlockBundle\SonataBlockBundle(),
new Knp\Bundle\MenuBundle\KnpMenuBundle(),
new Sonata\DoctrineORMAdminBundle\SonataDoctrineORMAdminBundle(),
new Sonata\AdminBundle\SonataAdminBundle(),
);
if (in_array($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;
}
public function registerContainerConfiguration(LoaderInterface $loader)
{
$loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
}
}
这个 composer.json 文件，

我也尝试更新作曲家，但由于这个问题也无法更新
【问题讨论】：
-
要更新内核，注释掉 AppKernel 中的类，然后更新。
-
真的很抱歉，但仍然遇到问题
Problem 1 - Installation request for sonata-project/doctrine-orm-admin-bundle ^3.0 -> satisfiable by sonata-project/doctrine-orm-admin-bundle[3.0.0]. - sonata-project/doctrine-orm-admin-bundle 3.0.0 requires sonata-project/adm in-bundle ^3.0 -> no matching package found. -
尝试在 composer.json 中添加 sonata-project/admin-bundle ^3.0 然后
-
在您的脚本中尝试在顶部添加类似这样的内容来导入类：使用 Sonata\DoctrineORMAdminBundle\NAME_OF_THE_CLASS 想法是在您能够使用之前导入类它。 Autoloader 会解决这个问题。
