The requested PHP extension ext-mysqli * is missing on php 7.2 on ubuntu 16.04 – Phpmyadmin

when I

composer create-project phpmyadmin/phpmyadmin

I got the problems:

- The requested PHP extension ext-mysqli * is missing from your system. Install or enable PHP's mysqli extension.

I had edit my php.ini and restart the php and nginx but still show the error?

sudo systemctl restart php7.2-fpm
sudo systemctl restart nginx

sudo nano /etc/php/7.2/fpm/php.ini

Do I need to install another mysqli? It’s so strange. I had install the
sudo apt-get install php7.2-fpm php7.2-mysql php7.2-cgi php7.2-common php-pear php7.2-mbstring
before and work well. But I don’t know why it has the problem when I reinstall the ubuntu and mariaDB and php 7.2 and phpmyadmin.
