出现以下错误是什么意思？

Warning: require(D:\ServerWeb\home/data/config.inc.php) [function.require]: failed to open stream: No such file or directory in D:\ServerWeb\home\checkappid.php on line 3

Fatal error: require() [function.require]: Failed opening required 'D:\ServerWeb\home/data/config.inc.php' (include_path='.;C:\php5\pear') in D:\ServerWeb\home\checkappid.php on line 3


这是我在运行checkappid.php时候出现的错误
