    If you are using Ubuntu 16.04, you can try check out this [link](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-composer-on-ubuntu-16-04) – Adlan Arif Zakaria Feb 26 '18 at 15:57

Your screenshot says: "phpunit required ext-dom" ..

That means, you have to install PHP-XML extension in order to get phpunit and Laravel properly installed.

  • @VasimVanzara you need to read the error messages. "NO SUCH FILE OR DIRECTORY" means that there's no file called "`artisan`" inside your `/opt/lampp/htdocs/first-project/` directory. You need to install the PHP extension `php-xml` in order to properly install Laravel. – lucasvscn Feb 27 '18 at 12:00

You are missing the correct extension for PHP try installing 

sudo apt-get install php7.1-dom

You may also need to install other packages to get everything to update.

Take a look at this link may help you https://askubuntu.com/questions/795629/install-php-extensions-in-ubuntu-16-04

You are missing ext-dom, php7.1-xml has the packages you need, try installing it by running:

sudo apt-get update
sudo apt-get install php7.1-xml

Then run this command:

composer install

If you don't have a composer you can follow this link from Digital Ocean which is very clear.

You can also refer their tutorial which is How To Deploy a Laravel Application with Nginx on Ubuntu 16.04.
