当使用后面的测试代码是报错。Warning: require_once(Mail.php) [function.require-once]: failed to open stream: No such file or directory in C:\wamp\phpDemo\index.php on line 2

Fatal error: require_once() [function.require]: Failed opening required 'Mail.php' (include_path='.;C:\php5\pear') in C:\wamp\phpDemo\index.php on line 2
而查看phpinfo时发现"include_path .;C:\php5\pear" 而我的include_path中已经改了。求大神解答。
