The error “laravel/installer v2.0.1 requires ext-zip * -> the requested PHP extension zip is missing from your system”. This error is something you can encounter when you install Laravel on a fresh Apache installation. Before you install the extension you should be aware of what version of PHP you have. If you have PHP 7, this is the command I used to install it.
sudo apt-get -y install php7.0-zip
