通过做两件事解决了问题

已从中删除主呼叫

/**
 * Initialize the activation works of the plugin.
 */
function awraq_activate_plugin()
{
    //removed 
}

register_activation_hook(__FILE__, \'awraq_activate_plugin\');

已将呼叫添加到；plugins\\u loaded“插件加载”；

/**
 * Initialize the plugin.
 */
function awraq_init_plugin()
{
    if (Init::activate() != TRUE) {
        deactivate_plugins(plugin_basename(__FILE__));
        //added below
        Notice::error(\'Plugin got Deactivated. Please check the dependencies.\', true);
    }
}
add_action(\'plugins_loaded\', \'awraq_init_plugin\');

在移除的类上__CLASS__ 具有完整的命名空间和类-private static $globalScopeName = \'Awraq\\Base\\Notice\';, 因为它将从外部调用

namespace Awraq\\Base;

if (!defined(\'ABSPATH\')) exit;

class Notice
{
    private static $globalScopeName = \'Awraq\\Base\\Notice\';
    private static $class = \'\';
    private static $msg = \'\';

    public static function error($msg = \'error\', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? \'notice notice-error is-dismissible\' : \'notice notice-error\';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action(\'admin_notices\', array(self::$globalScopeName, \'awraq_notice\'));
    }

    public static function warning($msg = \'warning\', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? \'notice notice-warning is-dismissible\' : \'notice notice-warning\';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action(\'admin_notices\', array(self::$globalScopeName, \'awraq_notice\'));
    }

    public static function success($msg = \'success\', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? \'notice notice-success is-dismissible\' : \'notice notice-success\';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action(\'admin_notices\', array(self::$globalScopeName, \'awraq_notice\'));
    }

    public static function info($msg = \'info\', $is_dismissible = TRUE)
    {
        self::$class = ($is_dismissible == TRUE) ? \'notice notice-info is-dismissible\' : \'notice notice-info\';
        self::$msg = __($msg, AWRAQ_TEXT_DOMAIN);
        add_action(\'admin_notices\', array(self::$globalScopeName, \'awraq_notice\'));
    }

    public static function  awraq_notice()
    {

        $class  = self::$class;
        $msg    = self::$msg;

        if ($class == \'\' and $msg == \'\') {
            return;
        }

        printf(\'<div class="%1$s"><p>%2$s</p></div>\', esc_attr($class), esc_html($msg));
    }
}
