我最近在我的 Mac 上安装了 Laravel 以开始学习它，因为我听到了一些好消息。
我的第一个错误是在访问时/public/：
Laravel 需要 Mcrypt PHP 扩展。
然后我安装了php54-mcrypt并在昨天晚上继续学习。
然后我今天下班回家，点击“brew update”，然后出现同样的错误？
然后我运行 brewinstall php54-mcrypt来接收：
警告：php54-mcrypt-5.4.16 已经安装
然后我跑去brew doctor接；
警告：“config”脚本存在于您的系统或 Homebrew 目录之外。/configure 脚本通常会查找 *-config 脚本以确定是否安装了软件包，以及在编译和链接时要使用哪些附加标志。
如果配置脚本覆盖系统或 Homebrew 提供的同名脚本，则在路径中包含其他脚本可能会混淆通过 Homebrew 安装的软件。我们发现了以下“配置”脚本：
