我使用的是3.2版本，部署到sae上请问需要改哪些？index.php怎么改啊？我只加上了define('ENGINE_NAME','sae');define('STORAGE_TYPE','sae');define('APP_MODE','sae');在conf下也建立了config_sae.php
打开网页后显示错误：
Warning: require(/Think/Think.class.php) [function.require]: failed to open stream: Permission denied in ThinkPHP.php on line 94

Fatal error: require() [function.require]: Failed opening required '/Think/Think.class.php' (include_path='.:/usr/local/sae/php/lib/php/sae_std_lib:/usr/local/sae/php/lib/php/apibus_lib:/usr/local/sae/php/lib/php/pear') in ThinkPHP.php on line 94
之前在本地成功运行，放到SAE上就有问题，请问到底怎么回事啊？
