How to install Dream Factory


I have 32 bit Ubuntu 14.04 LTS os.So i am unable to install 64 bit Dream Factory.32 bit Dream Factory is not available.Then i try the git hub method.It is also not working.I cant change the os right now.So i have only one option to install DM by Git Hub.I download the DM from git hub.But when i am going to run there are many error coming.

When i am trying to run php artisan dreamfactory:setup command the below errors are coming.

Errors are :

PHP Warning: require(/var/www/html/dreamfactory-master/bootstrap/…/vendor/autoload.php): failed to open stream: No such file or directory in /var/www/html/dreamfactory-master/bootstrap/autoload.php on line 17
