brew install php55-intl失败，无法安装Composer

我正在尝试安装npm install && grunt，但它告诉我我需要作曲家 . 我正在尝试安装作曲家，但这取决于php55 .

我试过brew install php55，php55-intl，php56，php56-intl等 .

我正在阅读这里的说明：https://getcomposer.org/doc/00-intro.md

它声明对于Mac我应该只使用brew命令：

brew更新brew自来水homebrew / homebrew-php brew自制软件/ dupes brew自制软件/版本brew安装php55-intl #fails这里brew install homebrew / php / composer

我收到以下错误：

有谁知道另一种工作？我已经尝试过curl命令，但它们从未运行过，我无法在我的mac上运行exe .

谢谢！
