Try this URL:
试试这个网址：
http://[Server-IP]:8000/app_dev.php/en/lucky/number
http://[Server-IP]:8000/app_dev.php/en/lucky/number
There's a bug in the Symfony Book: they forgot the demo app support i18n.
Symfony Book 中有一个错误：他们忘记了演示应用程序支持 i18n。
Just add the "/en" parameter before the routing ones.
只需在路由参数之前添加“ /en”参数。
I know this question it's closed but I hope my answer can help others that are still facing this problem.
我知道这个问题已经结束，但我希望我的回答可以帮助仍然面临这个问题的其他人。

Sometimes is a cache problem. Try to remove devfolder from /project/var/cache/dev.
有时是缓存问题。尝试从 /project/var/cache/dev 中删除dev文件夹。
As authentictechsays, also you can try the command:
正如authentictech所说，您也可以尝试以下命令：
php bin/console cache:clear
php bin/console cache:clear
If you want to specify the environment, you should add the --env=prod property.
如果要指定环境，则应添加 --env=prod 属性。

You actually don't extend Symfony Controller class. It should be class LuckyController extends Controller
你实际上没有扩展 Symfony Controller 类。它应该是类 LuckyController extends Controller
// src/AppBundle/Controller/LuckyController.php
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;
class LuckyController extends Controller {
/**
* @Route("/lucky/number")
*/
public function numberAction() {
$number = rand(0, 100);
return new Response('<html><body>Lucky number: '.$number.'</body></html>');
}
}
EDIT:after all, the problem in this question was not in extending controller, so ignore my answer.
编辑：毕竟，这个问题的问题不在于扩展控制器，所以忽略我的回答。

I copied and pasted your controller in an existing Symfony project and the route immediately appeared. So nothing wrong with the controller.
我将您的控制器复制并粘贴到现有的 Symfony 项目中，该路由立即出现。所以控制器没有问题。
I also compared the routing.yml and it's the same.
我也比较了routing.yml，结果是一样的。
The only thing that's left is to check the folder structure and make sure you don't have different Symfony projects mixed together; maybe you're editing the right file but starting the web server from a different path.
剩下的唯一事情就是检查文件夹结构并确保您没有将不同的 Symfony 项目混合在一起；也许您正在编辑正确的文件，但从不同的路径启动 Web 服务器。
Check carefully or rebuild the project in a completely different path. Since you're testing with the embedded web server, you don't need to put your project into /var/www/html (in fact it's better not to).
仔细检查或以完全不同的路径重建项目。由于您正在使用嵌入式 Web 服务器进行测试，因此您无需将项目放入 /var/www/html（实际上最好不要这样做）。

In case someone else runs into this problem: for me the problem was twofold:
万一其他人遇到这个问题：对我来说，问题是双重的：
- i forgot to assign a namespace
namespace AppBundle\Controller; - i didn't add a use statement for the template
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
- 我忘了分配一个命名空间
namespace AppBundle\Controller; - 我没有为模板添加 use 语句
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

Had the same issue, but for a completely different reason than those shown here so far...
有同样的问题，但原因与目前显示的完全不同......
Somehow my demo wasn't defining a default locale. There appear to be a number of configurations that could address this, but I'm not familiar enough with Symfony yet to know the exact cause. My solution until then is to simply define the locale in the URL, for example:
不知何故，我的演示没有定义默认语言环境。似乎有许多配置可以解决这个问题，但我对 Symfony 还不够熟悉，尚不清楚确切原因。在那之前我的解决方案是简单地在 URL 中定义语言环境，例如：
/app_dev.php/en/lucky/number
/app_dev.php/ en/lucky/number

Extending the base class Controller did not work for me. To solve the problem I had to do the following change in web/app.php
扩展基类 Controller 对我不起作用。为了解决这个问题，我必须在 web/app.php 中做以下更改
$kernel = new AppKernel('prod', true);
Also I had to add 'en' in the url: http://scotchbox.demo/en/lucky/number
我还必须在网址中添加“en”： http://scotchbox.demo/en/lucky/number

If you're using apache server with Symfony 4 (not the Symfony server) just add :
如果您在 Symfony 4（不是 Symfony 服务器）中使用 apache 服务器，只需添加：
composer require symfony/apache-pack
作曲家需要 symfony/apache-pack
Don't forget to address your Document Root to

http://localhost:8080/SymfonyProject/web/app_dev.php/lucky/number
http://localhost:8080/ SymfonyProject/web/app_dev.php/lucky/number
It works for me. Change "SymfonyProject" with your project name folder or delete it if your project is pointed directly by the Server. Also pay attention to the port that works for you (localhost:8080). In my case is 8080, in your could be 8000 or something else.
这个对我有用。使用您的项目名称文件夹更改“SymfonyProject”，或者如果您的项目由服务器直接指向，则将其删除。还要注意适合您的端口 (localhost:8080)。在我的情况下是 8080，在你的情况下可能是 8000 或其他东西。
