使用 Anaconda 在 OS X 上安装 pygraphviz 时出错

Question

我正在尝试在 OS X 10.9.5 中安装 pygraphviz。我正在使用 Python 2.7.12 和 Anaconda 2.1.0。我已经安装了graphviz。

这是我在运行 pip install pygraphviz 时遇到的错误

  #include "graphviz/cgraph.h"
                               ^
  compilation terminated.
  error: command 'gcc' failed with exit status 1

我也试过跑步：

conda install --channel https://conda.anaconda.org/garylschultz pygraphviz

这没有给出任何错误，但 import pygraphviz 在 python 中仍然不起作用。

当我尝试在 python 中导入 pygraphviz 时，出现以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/safsafi/anaconda/lib/python2.7/site-packages/pygraphviz/__init__.py", line 54, in <module>

    import graphviz as gv

    import _graphviz

提前致谢。

在 Mac OSX 上，我解决了这个问题：

pip install graphviz
pip install --install-option="--include-path=/opt/local/include" --install-option="--library-path=/opt/local/lib" pygraphviz
