Predis Autoloader 不加载

Question

我使用 composer 将外部库添加到我的项目中 - 包括 Predis。

由于某种原因，可能没有生成 Predis，我总是收到：

Class 'Predis\Autoloader' not found

所以我深入研究了作曲家加载文件，发现了一些奇怪的东西如下：

这是我的 composer.json:

{
    "require": {
        "facebook/php-sdk": "@stable",
        "everyman/neo4jphp": "dev-master",
        "predis/predis": "1.1.*@dev",
        "aws/aws-sdk-php": "2.*"
    },

    "autoload": {
        "psr-0": {
            "PicoCore\": "",
            "PicoCore\Authentication\" : "PicoCore/authentication",
            "PicoCore\Aws\" : "PicoCore/aws",
            "PicoCore\Cache\" : "PicoCore/cache",
            "PicoCore\Database\" : "PicoCore/database",
            "PicoCore\Facebook\" : "PicoCore/facebook",
            "PicoCore\Objects\" : "PicoCore/objects",
            "PicoCore\Rest\" : "PicoCore/rest",
            "PicoCore\Configuration\" : "PicoCore/configuration",
            "PicoCore\Configuration\Api\" : "PicoCore/configuration/api",
            "PicoCore\Scripts\" : "PicoCore/scripts",
            "PicoCore\Times" : "PicoCore/times"
        }
    }
}

现在，我想看看为 Predis 生成的命名空间是什么样子的，所以我检查了 composer 文件夹中的 autoload_par4.php，它是这样的：

<?php

// autoload_psr4.php @generated by Composer

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);

return array(
    'Symfony\Component\EventDispatcher\' => array($vendorDir . '/symfony/event-dispatcher'),
    'Predis\' => array($vendorDir . '/predis/predis/PicoCore'),
);

现在，如果您注意到，您会看到 Predis 命名空间路径是 /predis/predis/PicoCore

（PicoCore 是我的应用程序命名空间）当它应该是

/predis/predis/src

当我手动更改它时 - 它工作正常，但问题是每当我更新作曲家时，它都会再次执行..

知道它为什么或从哪里获取路径以及为什么添加我的项目名称吗？

对了，我看了下predis的composer.json，修改了一下，现在变成了这样：

{
    "name": "predis/predis",
    "type": "library",
    "description": "Flexible and feature-complete PHP client library for Redis",
    "keywords": ["nosql", "redis", "predis"],
    "homepage": "http://github.com/nrk/predis",
    "license": "MIT",
    "support": {
        "issues": "https://github.com/nrk/predis/issues"
    },
    "authors": [
        {
            "name": "Daniele Alessandri",
            "email": "suppakilla@gmail.com",
            "homepage": "http://clorophilla.net"
        }
    ],
    "require": {
        "php": ">=5.3.9"
    },
    "require-dev": {
        "phpunit/phpunit": "~4.0"
    },
    "suggest": {
        "ext-phpiredis": "Allows faster serialization and deserialization of the Redis protocol",
        "ext-curl": "Allows access to Webdis when paired with phpiredis"
    },
    "autoload": {
        "psr-4": {"Predis\": "src/"}
    },
    "extra": {
        "branch-alias": {
            "dev-master": "1.1-dev"
        }
    }
}

问题是我添加了以下依赖：

"predis/predis": "1.1.*@dev"

虽然我需要：

"predis/predis": "1.0.1"
