I use mac os
I run the code:

python setup.py install 

But it didn't success
So I write the dirs:

include_dirs = "/Users/allenlee/Downloads/pygraphviz-master/pygraphviz"
library_dirs = "/Users/allenlee/Downloads/pygraphviz-master/pygraphviz"

But it cause the error

AllendeMacBook-Pro:pygraphviz-master allenlee$ python setup.py install

Could you help to solve it?Thanks a lot

Do you have the graphviz development files installed? On Ubuntu, for example, they are in a package called libgraphviz-dev. I don't know how one would install them on a Mac.

[hebijiandai]

I use pip install graphviz to install it ,maybe graphviz is the key point of this error

[bugamn]

Can you remove the dirs you wrote and post the error message?

EDIT: the dirs that you added should have the graphviz files (not pygraphviz). It seems that the problem is that you need to install graphviz, which isn't a python package, so I don't see how you would install it with pip.

OK ,I finish the job,thanks a lot!

Hi,
I'm using yosemite and I have installed grapghviz using Homebrew. But when I try to run 'pip install pygraphviz', I still encounter the same issue. (i.e)

pygraphviz/graphviz_wrap.c:2954:10: fatal error: 'graphviz/cgraph.h' file not found
#include "graphviz/cgraph.h"
^
1 error generated.
error: command 'cc' failed with exit status 1

Can you please elaborate on how to resolve the issue?

Having the same problem as @AgalyaLoganathan on OS X 10.11 El Capitan

EDIT: I managed to fix it by doing two things:

1. Install pygraphviz from setup.py like so:
   python setup.py install --include-path=/usr/local/Cellar/graphviz/2.38.0/include --library-path=/usr/local/Cellar/graphviz/2.38.0/lib
   I saw a note about issues detecting the path and the example given on the website I was looking at still didn't work because it had the include directory to "include" /graphviz, which is why it could not detect "graphviz/graphviz/cgraph.h". Just double check that this is the same version of graphviz (obviously this particular path is specific to OS X users using homebrew, but making sure that the correct path for lib and include is probably useful)
2. Make sure pydot2 is installed, and NOT pydot. After uninstalling pydot and installing pydot2, everything started working fine.

My problem was:

pip install pygraphviz
....
#include "graphviz/cgraph.h"
^
1 error generated.
error: command 'cc' failed with exit status 1
....

Fixed with:

/usr/local/Cellar/graphviz/2.38.0/include/graphviz> ln -s . graphviz

pip install pygraphviz
...
Successfully installed pygraphviz-1.3.1

[thedimlebowski]

Can be solved with

pip install --global-option=build_ext --global-option="-I/usr/local/Cellar/graphviz/2.38.0/include/"  --global-option="-L/usr/local/Cellar/graphviz/2.38.0/lib/" pygraphviz

Or with: (credits to http://www.alexandrejoseph.com/blog/2016-02-10-install-pygraphviz-mac-osx.html)

pip install --install-option="--include-path=/usr/local/Cellar/graphviz/2.38.0/include/graphviz"  --install-option="--library-path=/usr/local/Cellar/graphviz/2.38.0/lib/graphviz" pygraphviz

The original post was about mac os.

But with your windows install attempt either you are missing the graphviz package (or parts of it) or else the pygraphviz setup code is not finding your graphviz installation and you may need to explicitly set that.
