How to install Composer in MacOS

Install download the composer using the following curl command in the terminal:

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:

php composer.phar [composer commnad]

In order to make composer available globally, you have to move the recently downloaded composer.phar to local user’s bin folder as follow:

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

go to /usr/local/bin folder .

You can click Shift + Command + G to open the dialog to go to folder. move the recently downloaded composer.phar in the usr/local/bin folder.

We want to run Composer with having to be root al the time, so we need to change the permissions:

sudo chmod 755 /usr/local/bin/composer.phar

create a alias using command:

Next, we need to let Bash know where to execute Composer:

nano ~/.bash_profile

Add this line below to bash_profile and save

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

and then run this command:

source ~/.bash_profile

Finally, run: composer --version

Now, you can access the composer from the terminal simply using the composer command.
