致命错误：` 类 'Doctrine\Common\Cache\ArrayCache' 未找到。作曲家无法正常工作

Question

我已经开始收到有关缺少课程的错误（尽管它们存在），但我没有更改任何内容。我已经重新安装了作曲家和供应商。

有时我会收到错误消息：

在第 310 行的 <..>htdocs\type705c\src\bootstrap.php 中找不到类 'core\SomeClass'

有时会出现错误，即找不到教义ArrayCache：

致命错误：第 258 行的 C:\Bitnami\wampstack-5.6.30-2\apache2\htdocs\type705c\src\bootstrap.php 中找不到类 'Doctrine\Common\Cache\ArrayCache'

我只是不断删除供应商/作曲家目录，有时会出现一个或另一个错误。

一个类存在于 \vendor\doctrine\cache\lib\Doctrine\Common\Cache\ArrayCache.php

SomeClass 类存在于 \core

Bootstrap.php

 <..> 

    use Doctrine\ORM\Tools\Setup;
    use Doctrine\ORM\EntityManager;
    use Doctrine\ORM\Configuration;
    use Symfony\Component\Console\Application;
    use Doctrine\Common\Cache\ArrayCache;
    use Doctrine\Common\Cache\ApcCache;


    $entitiesPaths = array( __DIR__.'/Bundle/Entity' );
    $proxiesPaths = array( __DIR__.'/Bundle/Proxies' );


    if ($isDevMode) {
        $cache = new \Doctrine\Common\Cache\ArrayCache;
    } else {
        $cache = new \Doctrine\Common\Cache\ApcCache;
    }

    $config = new Configuration;
    $config->setMetadataCacheImpl($cache);
    $driverImpl = $config->newDefaultAnnotationDriver($entitiesPaths);
    $config->setMetadataDriverImpl($driverImpl);
    $config->setQueryCacheImpl($cache);
    $config->setProxyDir($proxiesPaths);
    $config->setProxyNamespace('DoctrineProxies\__CG__\Bundle\Proxies');

    if ($isDevMode) {
        $config->setAutoGenerateProxyClasses(true);
    } else {
        $config->setAutoGenerateProxyClasses(false);
    }
    <..>

$some='some';
echo "<br> 307 ".$some; //echoes if ArrayCache is found, else do not 

use core\SomeClass;
$ecind = new SomeClass(); 

此时，如果ArrayCache没有错误，就会出现core\SomeClass.php丢失的错误，而我在autoload_static.php中没有看到它，因此它确实丢失了。

我总是使用同一个 composer dump-autoload 来生成命名空间。

autoload_static.php（以防ArrayCache 未找到。）

Answer 1

原因是，

我无意中将核心文件夹移动到另一个位置，因此 composer.json 没有指向正确的文件夹并且找不到类。

而不是/src/core 我不小心从/src 移动到/core
