Magento 2 SQLSTATE [HY000] : General error: 1823 Failed to add the foreign key constraint

Question

大家好，我的 Magento 2 Store 出现错误。例如 API 请求失败，Swagger 给出 500，样式表和 JS 文件无法加载等。

最后，我找到了使用新主题文件创建新 Magento 安装的最佳解决方案，只需复制 pub/media从文件并使用维护模式删除所有以 customers_ 为前缀的表, catalog_ , sales_和 eav_
这一步使我的新商店工作得很好，但我遇到了新的错误..我无法运行 setup:upgrade它显示一条消息:

[PDOException] SQLSTATE[HY000]: General error: 1823 Failed to add the foreign key constraint 'porosec_pororom/CAT_CTGR_PRD_CTGR_ID_CAT_CTGR_ENTT_ENTT_ID' to system tables

运行时出错 php -f bin/magento setup:db-schema:upgrade


上一条消息发生的命令



也当我跑 composer update它更新了许多依赖项，但它需要运行 setup:upgrade .

Swagger 错误 500

如果你备份了同一张表，如果外键约束和bkp表一样，当前表mysql会抛出异常，那么修改约束名或者删除现有的约束。

约束名称不应相同。
