线上购物.不能运行安装脚本

我试图为我的模块运行安装脚本，这是我第一次，但它没有运行，我可以在core_resource表中找到我的模块。模块版本为:

<Mdg_Gift>
    <version>0.1.0</version>
 </Mdg_Gift>

和安装程序名称是:

mysql4-install-0.1.0.php

我在app/code/core/Mage/core/Model/Resource/Setup.php中找到了这个代码区域

$resModel   = (string)$this->_connectionConfig->model;
$modName    = (string)$this->_moduleConfig[0]->getName();
$filesDir   = Mage::getModuleDir('sql', $modName) . DS . $this->_resourceName;
 if (!is_dir($filesDir) || !is_readable($filesDir)) {
 return array();
 }

，打印出$filesDir，其值为:

G: ' XAMPP ' XAMPP '根'柑橘' app ' ' '目标代码' ' sql '礼物mdg_gift_setup

路径错误，缺少本地代码池，我不知道该怎么办。如有任何帮助，我将不胜感激。

Config.xml文件是:

我也不能路由到IndexController.php文件，我的代码中有任何错误这里是我的IndexController.php文件:

<?php
class Mdg_Gift_IndexController extends Mage_Core_Controller_Front_Action{
    public function indexAction()
    {
        echo 'This is our test controller';
    }
}

/app/etc/模块/Mdg_Gift.xml:

<config>
    <modules>
        <mdg_gift>
            <active>true</active>
            <codePool>local</codePool>
        </mdg_gift>
    </modules>
</config>
