这是我的wp配置中的内容。php：

if ( !defined(\'ABSPATH\') )
    define(\'ABSPATH\', dirname(__FILE__) . \'/\');

我正在从plugin/pluginName目录呼叫：

require_once( ABSPATH . \'wp-includes/user.php\');

但它正在回归：

Warning: require_once(ABSPATHwp-includes/user.php) [function.require-once]: failed to open stream: No such file or directory in /home/------/wp-content/plugins/---/---.php on line 43

Fatal error: require_once() [function.require]: Failed opening required \'ABSPATHwp-includes/user.php\' (include_path=\'.:/usr/lib/php:/usr/local/lib/php\') in /home/------/wp-content/plugins/---/---.php on line 43

知道我为什么会犯这个错误吗？有什么解决方案吗？谢谢

require realpath(\'../../../wp-includes/class-phpass.php\');
