浏览器出现:HTTP ERROR 500

以下为错误日志；

PHP message: PHP Fatal error:  require(): Failed opening required '/home/www/imooc/tp5/public/../vendor/autoload.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/www/imooc/tp5/public/index.php on line 15" while reading response header from upstream, client: 192.168.2.219, server: tp6test.imooc, request: "HEAD / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "tp6test.imooc"

然后我看了看文件目录 并没有/../vendor/autoload.php'
