How to resolve errors while installing magento 2 for the first time with php, nginx and mysql

Question

I am trying to setup Magento 2 on my windows 10 machine via Ubuntu WSL. As of yet I have successfully installed PHP 7.4, MySQL 8.0 and NGINX. While installing Magento 2, I get the following error -

I am following the guide provided in link - https://www.simicart.com/blog/magento-2-nginx/#Step_4_Configure_nginx . I am getting the error while executing the step 7 in guide.

I tried researching these errors but all are pointing towards an issue in upgrade while this is a first time I am installing magento. I proceeded to executing step 8 but still getting the same set of errors.

Answer 1

Could you please run this and paste the output?

php -m

I took a quick look at that guide and it doesn't seem that it tells you to install all the necessary PHP extensions for Magento 2.

P.S. There are two different steps #7 in the guide. If you are stuck in the second one, run the following command and post the output here:

sudo systemctl status nginx
