我试图安装Facebook PHP SDK与作曲家。这就是我得到的结果
$ 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.
问题是，我有卷曲扩展启用(未注释在php.ini)。当我运行phpinfo()时，它说它已启用。 我唯一的线索是，当我运行$ php -m， '卷曲'行是缺失的，但我不知道该怎么做。
我在Win8上有wamp 2.4，我在cmd.exe中运行作曲家。
