Composer - The zip extension and unzip command are both missing

Issue

I was install php-image-resize library using composer and got the following error message:

composer require gumlet/php-image-resize
Failed to download gumlet/php-image-resize from dist: The zip extension and unzip command are both missing, skipping.

Solution

From the error message, php-zip package is missing. So, I installed it using the following command.

apt-get install -y php-zip
