Composer install error - requires ext_curl when it's actually enabled

Question

I\'m trying to install Facebook PHP SDK with Composer. This is what I get

$ composer install
Loading composer repositories with package information
Installin         


        

Answer 1

I had this problem after upgrading to PHP5.6. My answer is very similar to Adriano's, except I had to run:

sudo apt-get install php5.6-curl

Notice the "5.6". Installing php5-curl didn't work for me.
