symfony - Guzzle 安装

Question

我不确定为什么会收到此错误:

php composer.phar require guzzle/guzzle:~3.7

错误 :

    ./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
    - guzzle/guzzle v3.8.1 requires ext-curl * -> the requested PHP extension curl is  missing from your system.
    - Installation request for guzzle/guzzle ~3.7 -> satisfiable by guzzle/guzzle[v3.7.0, v3.7.1, v3.7.2, v3.7.3, v3.7.4, v3.8.0, v3.8.1].


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

任何的想法 ？？!

Answer 1

guzzle/guzzle v3.8.1 requires ext-curl * -> the requested PHP extension curl is missing from your system.

只需安装 cURL extension .在 Debian/Ubuntu 上: sudo apt-get install php5-curl .不要忘记重新启动您的 Web 服务器/PHP 进程。
