Error while installing PyGraphviz (Mac OS X, Anaconda)
Question: I'm having trouble while installing PyGraphviz. I'm using Anaconda in Mac OS
X.

Error messages indicates some reasons, but I already checked out it is
installed in anaconda directory.

    
    
    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
    

According to the error messages, How can I change the the include_dirs and
library_dirs variables in setup.py??

Here is the error message that I meet

        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

Answer: try the following (make sure to have anaconda-client installed and updated):

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