How to Install Composer 2.6.6?

If you realize you don’t have composer in your system here is an easy guide of how you can install composer 2.6.6.

To quickly install Composer in the current directory, run the following script in your terminal.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

In the next command you need to get “Installer verified”, if you get “Installer corrupt” try again.

php -r "if (hash_file('sha384', 'composer-setup.php') === 'e21205b207c3ff031906575712edab6f13eb0b361f2085f1f1237b7126d785e826a450292b6cfd1d64d92e6563bbde02') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php

php -r "unlink('composer-setup.php');"

Then, you most likely, you want to put the composer.phar into a directory on your PATH, so you can simply call composer from any directory (Global install), using for example:

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