未找到“ZendSearch\Lucene\Lucene”类 ZendFramework2

Question

我已经使用这些命令安装了 ZendSearch 和 composer：

$ cd /var/www/CommunicationApp/vendor/
$ git clone https://github.com/zendframework/ZendSearch.git
ZendSearch
$ cd ZendSearch/
$ curl -s https://getcomposer.org/installer | php
$ php composer.phar install

我已经按照GITHUB 安装了 Zendskeleton 所以，我不知道我在这里缺少什么。

比，在同一个 book 中，它教如何使用 ZendSearch，但我没有得到相同的结果，而是我得到一个致命错误：致命错误：类 'ZendSearch\Lucene\Lucene' 不是在第 107 行的 /var/www/CommunicationApp/module/Users/src/Users/Controller/SearchController.php 中找到

Answer 1

这本书给了你奇怪的指示，因为它说 Zend Search 不能通过安装。作曲家，但这不再是这种情况并不完全正确。修复：

1. 删除您的vendor 文件夹
2. 编辑您的composer.json 并将zendframework/zendsearch 添加到要求部分
3. 运行php composer.phar install 安装所有包（包括Zend Search）

那么一切都应该正常工作。

编辑：好的，由于某种原因，这个包没有在 packagist 上列出。您还需要将 repo URL 添加到您的 composer.json：

"repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/zendframework/ZendSearch"
    }
],

然后再试一次。

Answer 2

你应该把zendsearch放在vendor文件夹的zendframework中，按照书上说的安装好后，你应该在vendor/composer/autoload_namespaces.php末尾插入这一行：

'ZendSearch' => array($vendorDir . '/zendframework/zendsearch/library')
