我对Magento Development相当新，并且无法使用自定义运输模块。我遵循了许多教程，但每次都遇到类似的错误。我目前使用的是here。我对它进行了很多修改，但结果却出现了更多的错误，因此我目前将本教程的内容复制到我的magento 1.12.0.2安装中。
在Sysytem->Config->Shipping Methods下，新方法Smashing Magazine Carrier出现，我可以编辑显示的值。但是，每当我尝试前往前端的购物车时，我都会收到错误消息：
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
我很茫然，我正在寻找任何正确方向，以便解决这个问题。谢谢你的阅读！以下是相关文件：
