祝大家有美好的一天，

我在尝试在 OS X 10.9 中编译和安装 Pygraphviz 1.2 时出错

我已经从https://pypi.python.org/packages/source/p/pygraphviz/pygraphviz-1.2.zip#md5=90c728a8db276eede4e3af2f990a8985下载了 pygraphviz 存档

从我输入的终端

sudo ./setup.py install

输出是：

Trying pkg-config

clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
error: command 'cc' failed with exit status 1

如您所见，我已经使用 Homebrew 安装了 graphviz。

错误在clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]

来自clang 错误的解决方案：未知参数：'-mno-fused-madd'（python 包安装失败）是：

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
