组件安装错误：JInstaller :: Install：文件不存在

Question

我只是按照这个video创建了一个组件。我创建了名为admin.zip的组件。我在joomla 3.0中安装时收到以下警告。

警告

JInstaller ::安装：文件不存在C：\ wamp \ www \ Content \ tmp \ install_52009de34a2c1 \ site \ language \ en-GB.com_helloworld.ini

JInstaller ::安装：文件不存在C：\ wamp \ www \ Content \ tmp \ install_52009de34a2c1 \ admin \ language \ en-GB.com_helloworld.ini

我在组件菜单下获得helloworld组件。但是当我点击它时它会给我错误。它应该显示我在视频中显示的Hello world。

我的wamppserver版本是2.4并使用joomla 3.0。

我怎么能纠正这个问题

The error while clicking on hello world component is like this

我的helloworld.xml文件包含此代码

<?xml version="1.0" encoding="utf-8"?>

            </languages>            
    </administration>

 </extension>

在我的helloworld.php中，我有这个代码

<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');

// import joomla controller library
jimport('joomla.application.component.controller');

// Get an instance of the controller prefixed by HelloWorld
$controller = JController::getInstance('Helloworld');

// Perform the Request task
$input = JFactory::getApplication()->input;
$controller->execute($input->getCmd('task'));

 // Redirect if set by the controller
  $controller->redirect();
  ?>

更新

我在joomla 2.5中成功地做到了这一点，但它在最新版本的joomla中无效。我该怎么做才能让它在joomla 3.0中运行

Answer 1

检查您是否已将此代码添加到XML：

<languages>
        <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworld.ini</language>
        <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworldt.sys.ini</language>
</languages>

和：

<administration>
... 
    <languages>
            <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworld.ini</language>
            <language tag="en-GB" client="site">language/en-GB/en-GB.com_helloworld.sys.ini</language>
    </languages>
...
</administration>

并检查文件是否包含在您的安装ZIP中 - 在右侧文件夹中，例如：

language / en-GB / ...

请注意，您的扩展程序的文件路径可能会有所不同。

Answer 2

您缺少xml文件路径中的en-GB子文件夹声明。 xml：language / en-GB.com_helloword.sys.ini，它应该是language / en-GB / en-GB.helloworld.sys.ini和path：language / en-GB / en-GB.helloworld.sys.ini当然，相同的模式适用于其他语言文件。

*由于您的编辑和源代码包含，包括带有更正的完整xml代码（文件路径和扩展名结束标记）

`（不能包含扩展开关标签，由于某种原因不能打印，请确保正确包含它们）

对于您的其他问题，在您的helloworld.php中，您可能需要导入joomla控制器库：

jimport('joomla.application.component.controller');

之后

defined('_JEXEC') or die('Restricted access');

并替换这个：

$controller = JController::getInstance('Helloworld');

这一个：

$controller = JControllerLegacy::getInstance('Helloworld');
