A global installation of composer exists, however, customers will not have access to update it/modify it. If the
globally installed composer version will not work for you, you can always maintain your own installation of
composer for use under your own webspace. This way, you will be able to update/rollback composer as needed to the
specific versions that fit your needs.
To Install your own instance of composer within your visuaFUSION hosting space:
1. SSH into your web hosting space
2. run the following to navigate to your home directory:
cd ~
3. run the following:
curl -sS https://getcomposer.org/installer | php -d "disable_functions="
4. you can now use your own instance of composer with the following:
php -d "disable_functions=" ~/composer.phar <composer arguments>
