Hi guys, for 3 days I have been trying to get Magento working but it always results in errors of what kind. Can someone please guide me through the process?
I am using Ubuntu 18.04 LTS with Nginx 1.14. HTML and Javascript websites are working fine, a sample PHP file with phpinfo() in it works fine too. I am using PHP7.4 FPM by the way.
I just installed Composer so this should be the latest version available on Ubuntu too. The version is 1.6.3.
I then used composer to create a new Magento 2.4 project. This work fine untill it gets to:
Installing laminas/laminas-dependency-plugin
I then receive multiple errors like this:
PHP Fatal error: Uncaught Error: Undefined class constant 'PRE_COMMAND_RUN' in /var/www/sharemypatches.com/magento2/vendor/laminas/laminas-dependency-plugin/src/DependencyRewriterPlugin.php:63

Can anyone help me out on this matter please?
EDIT:
As it seems, for what ever reason my Ubuntu would automatically install an older version of Composer so I manually installed the newest version and that solved the problem(s)!
I did this:
composer -V
sudo apt remove composer
cd /tmp
wget http://getcomposer.org/download/1.10.5/composer.phar
php composer.phar -V
sudo mv composer.phar /usr/bin/composer
sudo chmod 750 /usr/bin/composer
composer -V
