我不知道如何启用我的开发环境

Question

每当我试图切换到我的dev环境，我的网站崩溃，没有任何错误(即使在apache日志中)

当我尝试运行composer update时，我总是遇到这个问题：

探查器服务"web_profiler.controller.profiler“依赖于一个不存在的服务”Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException“。

下面是我的AppKernel的内容

<?php

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

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
//            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
//            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
//            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
//            new JMS\AopBundle\JMSAopBundle(),
//            new JMS\DiExtraBundle\JMSDiExtraBundle($this),
//            new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
            new Zepluf\Bundle\StoreBundle\StoreBundle(),
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
//            $bundles[] = new Acme\DemoBundle\AcmeDemoBundle();
            $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)
    {
        $loader->load(__DIR__.'/config/config_'.$this->getEnvironment().'.yml');
    }
}

我的composer.json：

    "extra": {
        "symfony-app-dir": "app",

}

我想知道发生了什么，我如何才能解决这个问题？

Answer 1

为了回答我自己的问题，如果我想使用web_profiler，我需要在配置文件中将分析器设置为打开。

所以我在我的config_dev.yml中使用了类似这样的东西：

framework:
  profiler: { only_exceptions: false }
