Problem installing laravel(Ubuntu) - phpunit/phpunit 57 requires ext dom the requested PHP extension

i'm trying to install laravel with composer on my ubuntu 16.04. But i'm getting an error like this :

--
Your requirements could not be resolved to an installable set of packages.

phpunit/phpunit 5.7 requires ext dom the requested PHP extension.
--

how to solving?
just install php-xml with :
sudo apt-get install php5.6-xml (for php5.6)
or
sudo apt-get install php-xml (for php7)

My PHP version is "PHP 7.4.3", and I used this command
sudo apt-get install php7.4-xml

It worked!

Thank you brother <3
