install composer globally using mamp's PHP

gistfile1.txt

Create an alias for our bash profile.

Within the terminal, run:

nano ~/.bash_profile

add the following line:

alias phpmamp='/Applications/MAMP/bin/php/php7.3.1/bin/php'

you must use the version of php you currently use with your mamp installation

run the following command in the terminal:

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

Note that instead of the standard 'php' , we are use 'phpmamp' to use the MAMP installation of PHP.

to make this available globally, so we need to move the file to '/usr/local/bin/composer'. 

To do this, run the following command:

sudo mv composer.phar /usr/local/bin/composer

Terminal will ask you for yor password, after entering it and pressing the 'return' (or enter) key, you'll have a working global installation of composer on your mac that uses MAMP!

You can verify your installation worked by typing the following command:

composer

that's it.
