Как устранить ошибку при установке Composer'a?

Возникла потребность в использовании библиотеки instagram-php-scraper (https://github.com/postaddictme/instagram-php-scraper)
1) скачал
2) скачал php (windows.php.net VC11 x64 Thread Safe (2017-Jan-19 07:07:56))
3) Установил на C:\php
4) Скачал vc_redist.x64.exe установил
5) скачал composer.phar и заюзал php composer.phar install и даже скачал потом просто композер и установил
6) В библиотеке instagram-php-scraper есть файл composer.json
7) пытаюсь выполнить php composer.phar install или composer require mashape/unirest-php
Ошибка
composer require mashape/unirest-php
Using version ^3.0 for mashape/unirest-php
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- mashape/unirest-php v3.0.4 requires ext-curl * -> the requested PHP extens
ion curl is missing from your system.
- mashape/unirest-php v3.0.3 requires ext-curl * -> the requested PHP extens
ion curl is missing from your system.
- mashape/unirest-php v3.0.2 requires ext-curl * -> the requested PHP extens
ion curl is missing from your system.
- mashape/unirest-php v3.0.1 requires ext-curl * -> the requested PHP extens
ion curl is missing from your system.
- mashape/unirest-php v3.0.0 requires ext-curl * -> the requested PHP extens
ion curl is missing from your system.
- Installation request for mashape/unirest-php ^3.0 -> satisfiable by mashap
e/unirest-php[v3.0.0, v3.0.1, v3.0.2, v3.0.3, v3.0.4].

To enable extensions, verify that they are enabled in your .ini files:
- C:\php\php.ini
You can also run `php --ini` inside terminal to see which files are used by PH
P in CLI mode.

Installation failed, reverting ./composer.json to its original content.

Можете как то пояснить?
