Magento Nofrills布局以编程方式不工作Magento 1.8.1

我正在努力掌握如何使用布局，偶然发现了艾伦·斯托姆的书《Nofrills Magento布局》（好书）

直到第19页，我已经阅读了这些示例，在高级块功能部分添加了一个新类

我已经按照示例创建了所有的文件和模板，但是我现在遇到了一个错误，在修复之前似乎无法继续

block类如下所示：

<?php
class Nofrills_Booklayout_Block_Helloworld extends Mage_Core_Block_Template
{
public function _construct()
{
        $this->setTemplate('helloworld.phtml');
        return parent::_construct();    
}
}
?>

<?php
class Nofrills_Booklayout_IndexController  extends Mage_Core_Controller_Front_Action
{
public function indexAction()
{
    $block_1 = new Mage_Core_Block_Text();
    $block_1->setText('Original Text');

    $block_2 = new Mage_Core_Block_Text();
    $block_2->setText('The second sentence');

    $main_block = new Nofrills_Booklayout_Block_Helloworld();
    //$main_block->setTemplate('../helloworld.phtml');

    $main_block->setChild('the-first',$block_1);
    $main_block->setChild('the-second', $block_2);

    //$block_1->setText('Wait, I want this text instead!');
    echo $main_block->toHtml();

}

    public function helloblockAction()
{
    $block_1 = new Mage_Core_Block_Text();
    $block_1->setText('Original Text');

    $block_2 = new Mage_Core_Block_Text();
    $block_2->setText('The second sentence');

    $main_block = new Nofrills_Booklayout_Block_Helloworld();
    //$main_block->setTemplate('helloworld.phtml');

    $main_block->setChild('the-first',$block_1);
    $main_block->setChild('the-second', $block_2);

    echo $main_block->toHtml();

}
}

<h1>hello world</h1>
<p>
<?php echo $this->getChildHtml('the-first'); ?>
</p><p>
<?php echo $this->getChildHtml('the-second'); ?>
</p>

如果任何人对我为什么会犯这个错误或我做错了什么有任何线索，我们将不胜感激

非常感谢

自动加载器正在尝试从

C:\xampp\htdocs\phmagento\includes\src\Nofrills\u Booklayout\u Block\u Helloworld.php中加载
Nofrills\u Booklayout\u Block\u Helloworld
类。您确定该文件存在吗？它应该包含第一个代码段中的块
 禁用编译并重新编译所有内容。感谢马吕斯的回复，我现在知道我哪里出错了。好吧，粘贴文件并将其重命名到该位置是可行的，但我不明白为什么这本书引用将文件添加到app/code/local/Nofrills/Booklayout/Block/Helloworld.php？有什么线索吗？这是模块内部模块的正确路径。通常，如果模块设置正确，它会从那里加载，但看起来编译模式已经打开。运行compiler.php时应该填充错误中的src路径-我建议阅读以了解更多信息。好的，我明白你的意思，我已经关闭了Alan指向的complitation模式，是的，它工作起来很有魅力。非常感谢你的帮助。
