php文件打开显示空白

查看nginx的日志错误信息如下：2016/03/22 18:59:40 [error] 20273#0: *11 FastCGI sent in stderr: "PHP message: PHP Warning: require_once(/home/dwj/phpblog/inc/../vendor/autoload.php): failed to open stream: No such file or directory in /home/dwj/phpblog/inc/blade.php on line 3
PHP message: PHP Fatal error: require_once(): Failed opening required '/home/dwj/phpblog/inc/../vendor/autoload.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/dwj/phpblog/inc/blade.php on line 3" while reading response header from upstream, client: 218.75.123.165, server: dwjdwj.cn, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "dwjdwj.cn"

个人感觉好像是路径问题，但是不知道该怎么改。求解答

用 function __autoload($class)

意思就是/home/dwj/phpblog/vendor/autoload.php这个文件不存在，你可能写错路径了。
另外，在php.ini中把错误提示打开，开发模式下屏蔽错误信息就是给自己找麻烦。
