composer install with php-fpm5.6

[jianxungao]

I met the following problems when I was trying composer install for my new project, it says:
Your requirements could not be resolved to an installable set of packages.
Problem 1 - The requested PHP extension ext-exif * is missing from your system. Install or enable PHP's exif extension.
Problem 2 - The requested PHP extension ext-gd * is missing from your system. Install or enable PHP's gd extension.
Would you please provide some suggestions?
