php – 为什么Symfony在prod环境中缺少dev bundle？

以下是我在AppKernel.php中添加它们的方法：

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new SymfonyBundleFrameworkBundleFrameworkBundle(),new SymfonyBundleSecurityBundleSecurityBundle(),// ...
        );

        if (in_array($this->getEnvironment(),array('dev','test'))) {
            $bundles[] = new SymfonyBundleWebProfilerBundleWebProfilerBundle();
            $bundles[] = new SensioBundleDistributionBundleSensioDistributionBundle();
            $bundles[] = new SensioBundleGeneratorBundleSensioGeneratorBundle();
            $bundles[] = new DoctrineBundleFixturesBundleDoctrineFixturesBundle();
            $bundles[] = new LiipFunctionalTestBundleLiipFunctionalTestBundle();
        }

        return $bundles;
    }
}

当我更新我的应用程序时,我运行php composer.phar install –no-dev –optimize-autoloader.这将安装开发环境不需要的所有要求,然后清除缓存.

但是,清除缓存失败,并显示以下消息：

PHP Fatal error:  Class 'DoctrineBundleFixturesBundleDoctrineFixturesBundle' not found in /my/project/app/AppKernel.php on line 29
Script SensioBundleDistributionBundleComposerScriptHandler::clearCache handling the post-install-cmd event terminated with an exception



  [RuntimeException]
  An error occurred when executing the "'cache:clear --no-warmup'" command.

这不仅是Doctrine Fixtures Bundle的一个问题.如果我改变顺序,那么Liip Functional Test Bundle会首先出现,那么错误将是关于该捆绑包的.

为什么我看到这个错误？为什么Symfony尝试访问这些包,即使我们明确没有在开发环境中(请注意–no-dev composer标志)？如果不必在生产机器上安装所有dev依赖项,我该怎么做才能使其消失？
