Python 2.7 在Mac OSX 10.8.5上安装rpy2

我正在尝试使用pip在Mac Mountain Lion（10.8.5）上安装rpy2：

sudo pip install rpy2

并获取以下错误消息：

clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

我的python版本是2.7.2，R版本是3.2.1

在一些帖子中，我读到我需要安装Xcode和命令行工具来解决这个问题，但我已经安装了这两个工具（Xcode 5.1.1）

（以下是在埃里克·阿佩尔特（Eric Appelt）的建议后添加的，我非常感谢他：）

我还尝试设置ARCHFLAGS以禁用错误消息：

任何帮助都将不胜感激

请尝试将

ARCHFLAGS=-Wno error=unused command line argument hard error in future sudo pip install rpy2

作为解决方法。抱歉-sudo应该放在第一位-

sudo ARCHFLAGS=-Wno error=unused command line argument hard error in future pip install rpy2

Hi Eric，非常感谢您的回答。不幸的是，它也不起作用。我得到了相同的错误，尽管前面有几个其他错误消息。为了方便起见，我在上面的主消息中添加了它们。你知道那里发生了什么吗？谢谢请尝试将
