I have an Debian 8 on server but and has got added PHP 7.2. I have set up a site and choosed php7.2 as php version. I have installed composer and got no error. I log in as root on server adn move to the directory that I want the app to be installed on and I get several error swhen I run a composer command for installing and app, it is all related to php version, it states that php 7 or newver is not avaliable. How can I fix this? Example error : https://gbp.cnv.to/usd/89.99 - phpunit/phpunit 6.5.9 requires php ^7.0 -> your PHP version (5.6.40) does not satisfy that requirement.
My guess is you have installed PHP 7.2 compiling yourself and not by installing the .deb packages from a repository? So the default version OS uses is still the old PHP, and composer uses that. Try: Code: update-alternatives --config php update-alternatives --config php-cgi I hope you are not using ISPConfig on that host, since it breaks if you change the PHP version. I do not compile PHP myself, it is so complicated that I do not trust I can get it working. Instead I apt-get install from Ondre Sury repository, but looks like he no longer provides packages for Debian 8 Jessie.
