OSX 10.10 PHP Composer 找不到所需的扩展 intl 和 mcrypt

Question

我正在尝试使用以下命令在 OSX 10.10 上创建蛋糕 PHP 应用程序：

php /usr/local/bin/composer.phar create-project --prefer-dist cakephp/app testapp 

当我这样做时，我收到以下错误：

Your requirements could not be resolved to an installable set of packages.

我已通过 pear/pecl 安装了 intl 扩展，但仍继续收到此错误。

请有人恢复我对 PHP 的信心。

您可能需要运行php5enmod intl 来激活PHP5 模块。 否则，请检查您是否已在 OS X 上正确的 PHP 安装中安装了intl：有一个标准的 OS X 版本，但如果您在 OS X 版本的旁边安装了 PHP 版本，请检查是否您的 $PATH 变量中有正确的 PHP。
