Magento 2使用数据脚本来添加属性。在Vendor/Module/Setup/Patch/Data文件夹中添加。php文件（例如：AddCustomerAttributes）
下面将添加一些客户属性。添加此bin/magento设置后：需要升级命令。
如果脚本文件被正确执行，当然还有eav属性表中的属性，那么将有一个条目添加到patch_list数据表中。

请让我知道如果你需要帮助与任何这方面的。

感谢以上使用补丁的解决方案。它的工作，我使用了相同的方法使用InstallData/UpgradeData。php根据我的要求
请检查我的答案这将保存数据库中的数据在表customer_entity_varchar和属性在eav_attribute。验证码：
