已安装照明/路由但没有ClassLoader

Question

我正在遵循以下教程

http://www.gufran.me/post/laravel-illuminate-router-package-in-your-application/

我的composer.json看起来像这样

{
    "name": "superior/siginin",
    "description": "Sign In Example",
    "authors": [
        {
            "name": "A G",
            "email": "ag@gmail.com"
        }
    ],
    "require": {
        "illuminate/routing":"*",
        "illuminate/events":"*"
    }
}

我的index.php看起来像这样..

<?php
/**
 * User: ag
 * Date: 2/27/17
 * Time: 10:08 AM
 */

require 'vendor/autoload.php';
require 'vendor/illuminate/support/helpers.php';
$basePath = str_finish(dirname(__FILE__), '/');
$controllersDirectory = $basePath . 'Controllers';
$modelsDirectory = $basePath . 'Models';

// register the autoloader and add directories
Illuminate\Support\ClassLoader::register();
Illuminate\Support\ClassLoader::addDirectories(array($controllersDirectory, $modelsDirectory));

对于某些奇怪的原因Illuminate\Support\ClassLoader未加载到我的页面

有没有人知道为什么会这样。它添加的Illuminate \ Routing版本为v5.4.13

根据api。它应该在那里。
