php --ini
nano /etc/php5/cli/php.ini (it could be different for you)
Search for memory_limit by (ctrl + w)
make memory_limit to -1 or 2G (depending on what you can increase to)
save by (ctrl + x) then enter

1. Firstly i find which php.ini is working because i was using multiple xampp, so using : php --ini
2. after that in that file i updated the memory_limit = -1
