我正在努力解决这个问题
当做了

php bin/console doctrine:schema:update --dump-sql

我越来越

In SchemaException.php line 108:
The table with name 'chris_test_sonata.page__block' already exists.

很明显，这个表并不存在于我的数据库中。为了确保它与缓存无关，我甚至用我刚创建的一个新数据库进行了操作，结果是一样的。
在项目中搜索page__block时，只找到此Map

/**
 * @ORM\Entity
 * @ORM\Table(name="page__block")
 * @ORM\HasLifecycleCallbacks
 */
class SonataPageBlock extends BaseBlock

因此，此表不应有其他Map。
我还有一个block.orm.xml

<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xsi="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

            <generator strategy="AUTO"/>
        </id>

    </entity>
</doctrine-mapping>

还有一些其他事件，但都在dev.log中
我还在symfony dev/pools的缓存文件中保存了该文件

<?php

namespace Symfony\Component\VarExporter\Internal;

return $getExpiry ? PHP_INT_MAX : Hydrator::hydrate(
    $o = [
        clone (($p = &Registry::$prototypes)['Doctrine\\ORM\\Mapping\\Entity'] ?? Registry::p('Doctrine\\ORM\\Mapping\\Entity')),
        clone ($p['Doctrine\\ORM\\Mapping\\Table'] ?? Registry::p('Doctrine\\ORM\\Mapping\\Table')),
        clone ($p['Doctrine\\ORM\\Mapping\\HasLifecycleCallbacks'] ?? Registry::p('Doctrine\\ORM\\Mapping\\HasLifecycleCallbacks')),
    ],
    null,
    [
        'stdClass' => [
            'name' => [
                1 => 'page__block',
            ],
        ],
    ],
    [
        $o[0],
        $o[1],
        $o[2],
    ],
    []
);

我不知道它出了什么问题，为什么Map不起作用。
