Macos 在Mac OS X 10.9上安装pygraphviz 1.2时出错（缺少库）

我正在使用MacOSX10.9。我已经安装了graphviz 2.36.0

下载pygraphviz 1.2后，我在setup.py中修改了变量“library_path”和“include_path”：

当我尝试使用

python setup.py install安装graphviz时，我收到以下消息：

library_path=/usr/local/lib/graphviz

有人知道我如何解决这个问题吗？
请确保您的XCode已更新到最新版本，然后尝试以下操作：

xcode-select --install

出现提示时，安装命令行工具。然后尝试重建

xcode-select --install
