Enabling/installing GD extension? --without-gd

Question

How does one enable (or perhaps I need to install) GD when my phpinfo() output in \"Configure Command\" says; --without-gd ?

I also have nothing in my phpinfo() outp

Answer 1

I've PHP 7.3 and Nginx 1.14 on Ubuntu 18.

# it installs php7.3-gd for the moment
# and restarts PHP 7.3 FastCGI Process Manager: php-fpm7.3.
sudo apt-get install php-gd

# after I've restarted Nginx
sudo /etc/init.d/nginx restart

Works!
