我在安裝PyGraphviz時遇到問題。 我在Mac OS X中使用了Anaconda。安裝PyGraphviz時出錯（Mac OS X，Anaconda）
錯誤消息指示某些原因，但我已經檢出它安裝在anaconda目錄中。
Sundongui-MacBook-Pro:site-packages sundong$ pwd
/Users/sundong/anaconda/lib/python2.7/site-packages
Sundongui-MacBook-Pro:site-packages sundong$ pip install graphviz --upgrade
Requirement already up-to-date: graphviz in /Users/sundong/anaconda/lib/python2.7/site-packages
根據錯誤消息，我該如何更改setup.py中的include_dirs和library_dirs變量？
以下是錯誤訊息，我滿足
Sundongui-MacBook-Pro:anaconda sundong$ pip install pygraphviz

Your Graphviz installation could not be found.
1) You don't have Graphviz installed:
Install Graphviz (http://graphviz.org)
2) Your Graphviz package might incomplete.
Install the binary development subpackage (e.g. libgraphviz-dev or similar.)
3) You are using Windows
There are no PyGraphviz binary packages for Windows but you might be
able to build it from this source. See
http://networkx.lanl.gov/pygraphviz/reference/faq.html
If you think your installation is correct you will need to manually
change the include_dirs and library_dirs variables in setup.py to
point to the correct locations of your graphviz installation.
The current setting of library_dirs and include_dirs is:
library_dirs=None
include_dirs=None
