Installation Error PHP version !

my php version is 7.2 but getting error while installing . installer shows msg to upgrade the php version 7.1+ . Whats wrong !! https://wp.me/ab8OJ3-NT https://wp.me/ab8OJ3-NS

Check your NGINX/Apache2 Config

Reload Apache/NGINX after you've done the update of your conf.

Both the webserver and command line PHP version must match.

If Composer complains about the version, it means the command line PHP is not up to date (check with php -v).

Depending on your host you might be able to use php 7.2 on the command line by calling php7.2 composer [...] instead of composer [...].

Maybe you like to try https://github.com/phpstatic/phpstatic.com, simple install with 7.2, 7.3, 7.4. never stop working after os upgrade errors.
