我将其范围缩小到magento/module-csp，将Magento\Csp\Model\BlockCache设置为configured_block_cache，因此将其设置在generated/Metadata/frontend.PHP（及其他）中

摘录自vendor/magento/module-csp/etc/di.xml:93：

...
<type name="Magento\Csp\Model\BlockCache">
    <arguments>
        <argument name="cache" xsi:type="object">configured_block_cache</argument>
    </arguments>
</type>
...

摘录自generated/Metadata/frontend.PHP：

...
'Magento\\Csp\\Model\\BlockCache' =>
array (
  'cache' =>
  array (
    '_i_' => 'configured_block_cache',),'dynamicCollector' =>
  array (
    '_i_' => 'Magento\\Csp\\Model\\Collector\\DynamicCollector','serializer' =>
  array (
    '_i_' => 'Magento\\Framework\\Serialize\\Serializer\\Json',...

我不知道为什么会出现此错误。

我已经在数据库中搜索了多种形式的单词缓存和/或csp

还有其他遇到类似情况并且知道解决方案的人吗？

解决方法

从Magento 2.3.4升级到2.4时遇到了相同的问题。查看现有的Magento 2.4环境后，我注意到“ app / etc / di.xml”中缺少以下几行：

<virtualType name="configured_block_cache" type="Magento\Framework\App\Cache">
    <arguments>
        <argument name="cacheIdentifier" xsi:type="string">block_html</argument>
    </arguments>
</virtualType>
<type name="Magento\Framework\View\Element\Context">
    <arguments>
        <argument name="cache" xsi:type="object">configured_block_cache</argument>
    </arguments>
</type>
<type name="Magento\Framework\DB\Adapter\SqlVersionProvider">
    <arguments>
        <argument name="supportedVersionPatterns" xsi:type="array">
            <item name="MySQL-8" xsi:type="string">^8\.0\.</item>
            <item name="MySQL-5.7" xsi:type="string">^5\.7\.</item>
            <item name="MariaDB-(10.2-10.4)" xsi:type="string">^10\.[2-4]\.</item>
        </argument>
    </arguments>
</type>
<type name="Magento\Framework\View\TemplateEngine\Php">
    <arguments>
        <argument name="blockVariables" xsi:type="array">
            <item name="secureRenderer" xsi:type="object">Magento\Framework\View\Helper\SecureHtmlRenderer\Proxy</item>
            <item name="escaper" xsi:type="object">Magento\Framework\Escaper</item>
        </argument>
    </arguments>
</type>

添加这些行并清除缓存后，错误将得到解决。我不确定为什么在升级到2.4时不添加这些行，而在安装全新安装时是为什么。
