未找到 Silex\Route::setPath()

Question

我正在开发一个新的 Silex 项目，但在安装到我的控制器提供程序的路由时遇到了问题。我之前在另一个项目中已经成功地做到了这一点，但是现在当我将以下路线放入app.php时：

$app->mount('/', new CommonController());
$app->mount('/feeds', new FeedsController());
$app->mount('/admin', new AdminController());

我收到一个致命错误：Fatal error: Call to undefined method Silex\Route::setPath() in [root]/vendor/symfony/routing/Symfony/Component/Routing/RouteCollection.php on line 255

编辑：
安装根路由时不会引发错误。仅当我添加 /feeds 或 /admin 时。
END EDIT

我不知道这可能来自哪里 - 我已经在我的其他工作项目中搜索了这个函数定义，但在代码中找不到它。我想我可能缺少composer.json 中的一个库，但我不确定它可能是哪一个 - 两个项目的文件几乎相同：

“破碎”composer.json：

{
    "require": {
        "php"                     : ">=5.3.3",
        "silex/silex"             : "dev-master",

        "symfony/yaml"            : "2.1.*",
        "symfony/config"          : "2.1.*",
        "kriswallsmith/assetic"   : "1.0.*",
        "twitter/bootstrap"       : "2.0.*",
        "doctrine/dbal"           : "2.2.*",
        "fate/silex-extensions"   : "dev-master",

    },
    "autoload": {
        "psr-0": {
            [autoload routes defined here]
        }
    }
}

同样，这甚至可能不是我问题的根本原因，只是我的直觉。谁能破译这里发生了什么？

第二次编辑：FeedsController.php

<?php

namespace Controllers;

use Controllers\CommonController;
use Silex\Application;
use Symfony\Component\HttpFoundation\Request;

class FeedsController extends CommonController
{

    public function connect(Application $app)
    {
        $controller = $app['controllers_factory'];

        $controller->get('/', function (Request $request, Application $app)
        {
            return 'Yay!';
        });

        return $controller;
    }
}

Answer 1

我已将问题缩小到供应商文件夹中的一个坏库，但我不能确定它是哪一个。我将正常工作的供应商文件夹复制到损坏的文件夹中，一切都开始工作了。

一旦我知道确切的问题是什么，我会更新这个答案。
