Question

我目前正在撰写使用Paypal自适应付款SDK的Prestashop付款模块。当我尝试安装我的模块时，出现以下错误：

[PrestaShop] Fatal error in module Configuration:
Cannot redeclare class Configuration

这是我的代码。 paypal sdk已正确安装并正常工作。

config.xml中

<?xml version="1.0" encoding="UTF-8" ?>
     <module>
     <name>MyPayments</name>
     <displayName><![CDATA[My module]]></displayName>
     <version><![CDATA[1.0]]></version>
     <description><![CDATA[Description of my module.]]></description>
     <author></author>
     <tab><![CDATA[payments_gateways]]></tab>
     <confirmUninstall>Are you sure you want to uninstall? You will lose all your settings!</confirmUninstall>
