有个错误，请求解答。

Warning: require(D:\wwwroot/thinkphp/base.php): failed to open stream: No such file or directory in D:\wwwroot\qudu.��ַ\index.php on line 8

Fatal error: require(): Failed opening required 'D:\wwwroot/thinkphp/base.php' (include_path='.;C:\php\pear') in D:\wwwroot\qudu.��ַ\index.php on line 8

上面提示这个怎么回事啊。
