When running any commands with "composer" in them, there is no output at all and it just fails to accomplish anything:
# composer OPTIONS
This issue might be caused by the Suhosin PHP extension either in EA-PHP or alt-php provided by CloudLinux.
If your server is running CloudLinux™ OS and the user is using CageFS, you'll want to follow CloudLinux's article on this subject here:
If you are not using CloudLinux, consider running the following command as root to whitelist the "phar" extension in Suhosin for your PHP version. You'll want to change "ea-php74" to the version of PHP that you intend to use.
echo "suhosin.executor.include.whitelist = phar" >> /opt/cpanel/ea-php74/root/etc/php.d/300-suhosin.ini
