尽管在我调试时路由存在，但无法为路由生成 URL

Question

我提出了这个异常：

RouteNotFoundException
RuntimeError
HTTP 500 Internal Server Error
An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "listecours" as such route does not exist.").

在我的树枝模板（包含path('listecours') 的行）的此时提出：

                       </li>
                        <li class="nav-item active">
                            <a href="{{ path('listexercices') }}" class="nav-link">Liste d'exercices</a>
                        </li>
                        <li class="nav-item active">
                            <a href="{{ path('listecours') }}" class="nav-link">Liste des cours</a>
                        </li>
                    {% else %}
                        <li class="nav-item active">
                            <a href="{{ path('listexercices') }}" class="nav-link">Liste d'exercices</a>
                        </li>

虽然路线是正确的（我想）在我的 CoursController 中使用注释声明：

<?php

namespace App\Controller;

use App\Repository\CoursRepository;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class CoursController extends AbstractController
{
    /**
     * @Route("/cours", name="cours")
     */
    public function index()
    {
        return $this->render('cours/index.html.twig', [
            'controller_name' => 'CoursController',
        ]);
    }

    /**
     * @Route("/listecours", name="listecours")
     */
    public function listeCours(CoursRepository $cours){
        return $this->render('cours/cours.html.twig', [
            'cours' => $cours->findAll()
        ]);
    }
}

php bin/console debug:router 行产生了这个输出，表明路由确实存在：

我仍然不明白为什么异常会无缘无故地被提出来，以至于它只是烦人。我对 Twig 代码中的其他路由做了完全相同的事情，并且在我添加最后一个之前它工作得非常好。

这里的目标是能够停止出现此异常并让路由正常工作。

请帮助实现这一目标？如果您想了解更多信息，请告诉我。

谢谢。

Answer 1

没有什么能真正解决这个非常烦人的“问题”，我尝试多次清除缓存，但没有任何效果。然后我看到有人说在用 composer 安装 apache-pack 之后就成功了。我试过了，它奏效了......去看看。

Answer 2

不添加apache-pack 的等效解决方案是在站点的http-vhosts.conf 或yoursite.conf 中使用以下内容（基于先前推荐的.htaccess）。 ：

    ServerName a.good.name
    DocumentRoot "..."
    <Directory "...">
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
        <IfModule mod_rewrite.c>
            Options -MultiViews
            RewriteEngine On
            RewriteCond %{REQUEST_URI}::$0 ^(/.+)/(.*)::\2$
# added by apache-pack, part 1
            RewriteRule .* - [E=BASE:%1]
            RewriteCond %{HTTP:Authorization} .+
            RewriteRule ^ - [E=HTTP_AUTHORIZATION:%0]
            RewriteCond %{ENV:REDIRECT_STATUS} =""
            RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
            RewriteCond %{REQUEST_FILENAME} !-f
            RewriteRule ^ %{ENV:BASE}/index.php [L]
# end, added by apache-pack, part 1
        </IfModule> 
    </Directory>
# added by apache-pack, part 2
    <IfModule !mod_rewrite.c>
        <IfModule mod_alias.c>
            RedirectMatch 307 ^/$ /index.php/
            # RedirectTemp cannot be used instead
        </IfModule>
    </IfModule>
# end, added by apache-pack, part 2
    <IfModule dir_module>
        DirectoryIndex index.php
    </IfModule>
