自定义Magento运输模块的致命错误


Fatal Error with Custom Magento Shipping Module

我是相当新的Magento开发和我有麻烦得到一个自定义运输模块的工作。我遵循了许多教程,但每次都以类似的错误告终。我现在用的是这个。我对它进行了很多修改,但最终出现了更多的错误,所以我目前将本教程的库存复制到我的magento 1.12.0.2安装中。

Sysytem->Config->Shipping Methods下,出现了新的方法Smashing Magazine Carrier,我可以编辑显示的值。然而,每当我试图去购物车的前端,我得到的错误:Fatal error: Call to a member function setStore() on a non-object in /var/www/includes/src/Mage_Shipping_Model_Shipping.php on line 421

和错误:Fatal error: Class 'Mage' not found in /var/www/includes/src/Mage_Core_Model_Resource_Setup.php on line 378

我不知所措,正在寻找任何正确方向的暗示来解决这个问题。感谢您的阅读!以下是相关文件:
