我现在在wordpress中教自己名称空间和OOP，对我来说太简单了。

在插件的底部，我正在加载激活和停用挂钩。目前，停用挂钩可以工作，但激活挂钩不能，它只是默默地失败(WP_DEBUG 已打开）。

基文件声明一个名称空间和一个常量，然后需要类文件来激活和停用，然后注册挂钩。激活和停用在功能上都是相同的，每个都需要并实例化一个错误日志记录类，并向一个方法发送消息。

我已经把这两方面的文件都翻了一遍register_deactivation_hook 对于register_activation_hook （特别是撰稿人指出）我还没能解决这个问题，所以如果你能想到为什么一个有效而另一个无效，我将不胜感激。

文件结构如下：

/plugin/
    plugin.php   
/plugin/includes/
         ActivatorClass.php
         DeactivatorClass.php
         ErrorLogClass.php

/插件/插件。php

function pluginInit() {

    // Machine file path
    define( \'PLUGIN_PATH\', realpath( plugin_dir_path( __FILE__ ) ) . DIRECTORY_SEPARATOR );

    /**

    * Documented in includes/ActivatorClass.php
    */
    require_once PLUGIN_PATH . \'includes/ActivatorClass.php\';
    register_activation_hook( __FILE__, array( __NAMESPACE__ . \'\\\\ActivatorClass\', \'activate\' ) );

    /**
