Project directory /home/bum/public_html/project-community-edition/ is not empty.
Error: Project directory /home/bum/public_html/project-community-edition/ is not empty. Cause: Directory where you want to install Magento or any application needs to be empty ie. there should be no contents. To check use the command: ls -a and remove unnecessary files so here folder project-community-edition is extra and we need to remove it so use command: rm -rv pro* you too can use the same command just change pro to initials of your folder name if you have multiple folders remove all by same.
