我正在尝试安装npm install && grunt，但是它告诉我需要composer。我正在尝试安装composer，但这取决于php55。
我已经尝试了brew install php55、php55-intl、php56、php56-intl等命令。
我正在阅读来自https://getcomposer.org/doc/00-intro.md的说明。
它指出对于Mac，我应该简单地使用brew命令：
brew update brew tap homebrew/homebrew-php brew tap homebrew/dupes brew tap homebrew/versions brew install php55-intl #在此处失败 brew install homebrew/php/composer 我得到以下错误：
安装php55-intl：
brew install php55-intl
安装php55-intl的依赖：php55, icu4c
下载http://www.php.net/get/php-5.5.15.tar.bz2/from/this/mirror，已经下载到/Library/Caches/Homebrew/php55-5.5.15

有人知道其他解决方法吗？我尝试了curl命令，但它们从未运行过，并且我无法在我的Mac上运行exe文件。
谢谢！
