I'm trying to install magento but I have a problem when I call the composer to install it. With the command 'composer install' I receive this two problems:
Problem 1
- The requested PHP extension ext-mcrypt * is missing from your system. Install or enable PHP's mcrypt extension.
Problem 2
- The requested PHP extension ext-intl * is missing from your system. Install or enable PHP's intl extension.
I read in the site and I find a solution related to the command 'sudo apt-get...' and also in this case, shell gives me an error saying that the command cannot be find. I saw around on internet and, sincerely, I don't understand some of the solution I read around. Are you able to explain to me how can I solve it? I will appreciate your help!
