我使用 composer 将外部库添加到我的项目中——包括 Predis。
出于某种原因，可能没有生成 Predis，我总是收到：
Class 'Predis\Autoloader' not found
所以我潜入作曲家加载文件并发现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，它都会再次这样做..
任何想法为什么或从哪里采用路径以及为什么添加我的项目名称？
顺便说一下，我查看了predis的composer.json并对其进行了更改，现在它看起来如下：
