index.php路径问题

这是错误日志的信息：
[Tue Apr 21 20:00:28.677167 2015] [proxy_fcgi:error] [pid 22003:tid 140096514742016] [client 101.80.24.18:49795] AH01071: Got error 'PHP message: PHP Warning: require(/var/www/pangwenli/test/public/../bootstrap/autoload.php): failed to open stream: No such file or directory in /var/www/pangwenli/dsfad/public/index.php on line 21\nPHP message: PHP Fatal error: require(): Failed opening required '/var/www/pangwenli/test/public/../bootstrap/autoload.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/pangwenli/dsfad/public/index.php on line 21\n'

我想问的是我访问的明明是dsfad目录，require路径为什么会跑到test？
ps. 我之前执行过composer update更新过某个包好像vendor/autoload.php这个文件里面的一串编码更新了。
