我曾经有 MAMP（http://www.mamp.info/en/index.html）。卸载它并通过 Macports 安装“MAMP”。
我完全删除了 /Applications/MAMP/ 文件夹。我现在想通过 pear 安装 PHPUnit。
梨安装：

/opt/local/bin/pear
> pear config-show

我已经删除了很多对 /Applications/MAMP/ 文件夹结构的引用（并且神秘地不断重新生成）。我想删除所有这些引用，但不确定应该是什么替代值。我似乎无法卸载 pear 或升级 pear。
理想情况下，我希望保持安装 pear 并安装 PHPUnit，以便我可以运行一些测试。
