magento2.3.x安装webpos插件报错

PHP Fatal error:  Cannot inherit previously-inherited or override constant MEDIA_GALLERY from interface MagestoreWebposApiDataCatalogProductInterface in E:phpEnvwwwmagentoappcodeMagestoreWebposModelCatalogProduct.php on line 33

Fatal error: Cannot inherit previously-inherited or override constant MEDIA_GALLERY from interface MagestoreWebposApiDataCatalogProductInterface in E:phpEnvwwwmagentoappcodeMagestoreWebposModelCatalogProduct.php on line 33

上传完毕之后执行

php bin/magento s:up && php bin/magento s:s:d -f

看了一下插件只支持2.2x 

如果要用在2.3x上面要怎么修改啊
