Php – Composer install error – requires ext_curl when it’s actually enabled

composer-phpcurlfacebook-php-sdkPHPwindows

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

$ composer install
Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

    Problem 1
        - Installation request for facebook/php-sdk dev-master -> satisfiable by facebook/php-sdk[dev-master].
        - facebook/php-sdk dev-master requires ext-curl * -> the requested PHP extension curl is missing from your system.

Problem is, I have curl extension enabled (uncommented in php.ini). When I run phpinfo(), it says it's enabled.
Only clue I have is that when I run $ php -m, 'curl' line is missing but I don't know what to do about it.

I have wamp 2.4 on Win8 and I'm running composer in cmd.exe.

This is caused because you don't have a library php5-curl installed in your system,

On Ubuntu its just simple run the line code below, in your case on Xamp take a look in Xamp documentation

sudo apt-get install php5-curl

For anyone who uses php7.0

sudo apt-get install php7.0-curl

For those who uses php7.1

sudo apt-get install php7.1-curl

For those who use php7.2

sudo apt-get install php7.2-curl

For those who use php7.3

sudo apt-get install php7.3-curl

For those who use php7.4

sudo apt-get install php7.4-curl

For those who use php8.0

sudo apt-get install php8.0-curl

Or simply run below command to install by your version:

sudo apt-get install php-curl
