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.
任何想法 ??!
