curl -sS https://getcomposer.org/installer | php

 
After the command, you will have composer.phar file in the current directory and the composer command is available as:

alias composer="php /usr/local/bin/composer.phar"

and then run this command:

 source ~/.bash_profile

Finally, run: composer --version
