Unable to install Shopware.

Namaste, I am trying to install Shopware in my LAMP 14.04, after the installation, I tried opening the address it redirects me to localhost/shopware-5.1.6/recovery/install/.

which returns the blank page.

I checked the error log, it shows me this error 

[Mon Oct 09 17:02:59.869370 2017] [:error] [pid 7940] [client ::1:45840] PHP Warning:  require_once(/var/www/html/Shopware/shopware-5.1.6/recovery/common/vendor/autoload.php): failed to open stream: No such file or directory in /var/www/html/Shopware/shopware-5.1.6/recovery/common/autoload.php on line 5, referer: http://localhost/Shopware/

Please help.

 

I solved this by reinstalling the shopware from the official site and did the configuration again.
