正如我在评论中提到的，在S3.3中，服务器命令已被移动到它们自己的WebServerBundle中。需要对 AppKernel.php 进行一些编辑才能激活捆绑包。我怀疑一旦3.3真正发布并且人们尝试升级，许多其他开发人员可能会遇到这种情况。

我不做任何承诺，但尝试更新AppKernel.php：

    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();
        }
    }

我没有一个好的测试项目可以尝试它，但至少应该显示命令。

如果有人想知道，我所做的就是安装一个新的开发项目，然后四处走动。

composer create-project symfony/framework-standard-edition s33 "3.3.*" --stability=dev

我也发现了这一点，但它没有提到需要更新AppKernel.php http://symfony.com/blog/new-in-symfony-3-3-webserverbundle

从升级指南中：https://github.com/symfony/symfony/blob/3.4/UPGRADE-3.3.md

server：run、server：start、server：stop 和 server：status console 命令已移至专用捆绑包。在 composer.json 中要求 symfony/web-server-bundle，并在 AppKernel 中注册 Symfony\Bundle\WebServerBundle\WebServerBundle 以使用它们。

只要您的 composer.json 中有 symfony/symfony，就无需向其添加 Web 服务器捆绑包。只需要调整 AppKernel 文件即可。

在启动服务器之前运行此命令。

composer require symfony/web-server-bundle --dev
