Question

当我运行composer update时，调用cache:clear脚本时出现以下错误。

> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache
PHP Fatal error:  Class 'Doctrine\Common\Inflector\Inflector' not found in /home/sarah/workspace/telematics_tracker/vendor/doctrine/common/lib/Doctrine/Common/Util/Inflector.php on line 29

Inflector.php位于正确的位置，包含以下内容。

namespace Doctrine\Common\Util;

use Doctrine\Common\Inflector\Inflector as BaseInflector;

/**
 * Doctrine inflector has static methods for inflecting text.
 *

 */
class Inflector extends BaseInflector
{
}

我在docblock Kept for backwards compatibility reasons, was moved to its own component中看到了评论。

有谁知道它被移到哪里了？

如何获取缓存：清除以调用正确的类？

Answer 1

今天早上运行composer update安装了新版本的doctrine / inflector Installing doctrine/inflector (1.2.x-dev e11d84c)，我不再收到此错误。

Answer 2

将您的php版本更新为7.2或更高版本

缓存异常错误：使用Class Doctrine \ Common \ Inflector \ Inflector
