composer create-project --prefer-dist laravel/laravel でプロジェクトを作成するとエラーになる対象方法が知りたい。

提示のコンソール画面ですがlaravelのプロジェクトを作成するとエラーになりますがこれはどう対処すればいいのでしょうか？

composer update

Composer is operating significantly slower than normal because you do not have the PHP curl extension enabled.
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires phpunit/phpunit 9.5.10 -> satisfiable by phpunit/phpunit[9.5.10].
    - phpunit/phpunit 9.5.10 requires ext-dom * -> it is missing from your system. Install or enable PHP's dom extension.

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/8.1/cli/php.ini
    - /etc/php/8.1/cli/conf.d/10-opcache.ini
    - /etc/php/8.1/cli/conf.d/10-pdo.ini
    - /etc/php/8.1/cli/conf.d/20-calendar.ini
    - /etc/php/8.1/cli/conf.d/20-ctype.ini
    - /etc/php/8.1/cli/conf.d/20-exif.ini
    - /etc/php/8.1/cli/conf.d/20-ffi.ini
    - /etc/php/8.1/cli/conf.d/20-fileinfo.ini
    - /etc/php/8.1/cli/conf.d/20-ftp.ini
    - /etc/php/8.1/cli/conf.d/20-gettext.ini
    - /etc/php/8.1/cli/conf.d/20-iconv.ini
    - /etc/php/8.1/cli/conf.d/20-phar.ini
    - /etc/php/8.1/cli/conf.d/20-posix.ini
    - /etc/php/8.1/cli/conf.d/20-readline.ini
    - /etc/php/8.1/cli/conf.d/20-shmop.ini
    - /etc/php/8.1/cli/conf.d/20-sockets.ini
    - /etc/php/8.1/cli/conf.d/20-sysvmsg.ini
    - /etc/php/8.1/cli/conf.d/20-sysvsem.ini
    - /etc/php/8.1/cli/conf.d/20-sysvshm.ini
    - /etc/php/8.1/cli/conf.d/20-tokenizer.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-dom` to temporarily ignore these required extensions.
