composer install会出错：
Problem 1
- guzzle/guzzle v3.9.3 requires ext-curl * -> the requested PHP extension curl is missing from your system.
- guzzle/guzzle v3.9.3 requires ext-curl * -> the requested PHP extension curl is missing from your system.
- Installation request for guzzle/guzzle v3.9.3 -> satisfiable by guzzle/guzzle[v3.9.3].
To enable extensions, verify that they are enabled in those .ini files:
- /opt/phpfarm/inst/php-5.4.45/lib/php.ini
我使用phpfarm用于多个php版本。在安装期间未指定设置（例如，configoptions="\ –with-curl \ ... "）。
如何解决此问题并安装扩展程序？
