我正在尝试使用以下命令在OSX 10.10上创建一个蛋糕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：

我已经通过梨/pecl 安装了 intl 扩展，但仍然继续收到此错误。
请有人恢复我对PHP的信心。
您可能需要运行 php5enmod intl 才能激活 PHP5 模块。否则，请检查您是否在OS X上安装了正确的PHP安装intl：有一个标准的OS X，但是如果您在OS X版本旁边安装了PHP版本，请检查$PATH变量中是否有正确的PHP。
