推荐答案
正如我在评论中提到的那样，在S3.3中，服务器命令已移至其自己的WebServerBundle.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实际发布并尝试升级，许多其他开发人员可能会遇到此问题.
As I mentioned in my comment, in S3.3 the server commands have been moved to their own WebServerBundle. Some editing of AppKernel.php is required to activate the bundle. I suspect that many other developers might run into this once 3.3 is actually released and people try upgrading.
我不做任何承诺，但尝试使用以下方法更新AppKernel.php:
I make no promises but try updating AppKernel.php with:
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();
}
}
我没有一个很好的测试项目来尝试它，但是至少应该显示命令.
I don't have a good test project to try it on but at least the commands should show up.
万一有人想知道的话，我所做的就是安装一个新的开发项目，并仔细研究一下.
And in case anyone is wondering, all I did was to install a fresh development project and poked around a bit.
composer create-project symfony/framework-standard-edition s33 "3.3.*" --stability=dev
我也发现了这一点，但没有提到需要更新AppKernel.php http://symfony.com/blog/new-in-symfony-3 -3-webserverbundle
I also found this but it does not mention the need to update 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控制台命令已移至专用捆绑包.在您的composer.json中要求symfony/web-server-bundle，并在AppKernel中注册Symfony \ Bundle \ WebServerBundle \ WebServerBundle 才能使用它们.
只要您的composer.json中包含symfony/symfony，就无需向其中添加Web服务器捆绑包.只需调整AppKernel文件即可.
As long as your composer.json has symfony/symfony in it then there is no need to add the web server bundle to it. Just need to adjust the AppKernel file.
