[Install.xml文件在opencart 3中将其作为扩展安装时不会更新php文件

Question

我正在从事一个opencart项目。在另一个开发人员实施的项目中，有一个新的模块调用折扣。我已将相关文件和相关方法复制到一个新项目中，并且效果很好。我已经创建了一个带有与Discount模块相关的新文件的discount.ocmod.zip文件，并且已经创建了install.xml文件来更新默认的php文件（我正在更新product.php），但是安装扩展程序后，文件将复制到正确的位置，但是product.php不会使用新功能进行更新。我在这里做错什么了？

这是修改日志。

这是我的xml文件：

<?xml version="1.0" encoding="UTF-8"?>

也许您可以尝试从XML文件中删除“-”：

<?xml version="1.0" encoding="UTF-8"?>
