I'm unable to install pygraphviz even after installing graphviz and ensuring that cgraph.h is present in the directory.

I've also manually specified the directory for install. e.g. install-path

fatal error C1083: Cannot open include file: 'graphviz/cgraph.h': No such file or directory

Looking for any and all suggestions. Using Windows.

C:\Users\mmcgown\Desktop\School\MSDS452\pygraphviz-1.5>python setup.py install --prefix=C:\Program_Files_(x86)\Graphviz2.38 --include-path=C:\Program_Files_(x86)\Graphviz2.38\include\ --library-path=C:\Program_Files_(x86)\Graphviz2.38\lib\

I installed the latest graphviz using the latest win64 executable from graphviz.org

graphviz 2.49 win64

then installation using the following command worked for me

pip install --global-option=build_ext --global-option="-IC:\Program Files\Graphviz\include" --global-option="-LC:\Program Files\Graphviz\lib" pygraphviz

  • Works perfectly, thanks! – Kevin Ramirez Zavalza Dec 07 '21 at 01:10
  • @KevinRamirezZavalza Let me know in comments if you face any issues in the future – codeslord Dec 09 '21 at 07:28
  • Worked for me using the latest graphviz at the time of writing (7.1.0) – Bruce Adams Feb 21 '23 at 16:33

    @codeslord Thanks for the suggestions. I had installed vs2022 community version but it did not work. Finally, I just thought to install via anaconda , and it worked for me . I really dnt know what was screwed up :( – Praveer Kumar Apr 26 '23 at 06:51

On Ubuntu please do
sudo apt install graphviz-dev

For those who visit this page, you may already come across to this fix or this issue on GitHub and try to install GraphViz2.38 manually. But neither of them will work since GraphViz and PyGraphViz are 2 different libraries

Mac or Ubuntu already have their solutions on GitHub, however for Win10 64-bit, it does not receive any fix yet since 2018. Installing pygraphviz on Windows 10 64-bit, Python 3.6

Someone have created a build of PyGraphviz 1.5 on his Anaconda channel for Windows 64 bit running Python 3.6, Python 3.7 or Python 3.8. If you're running Anaconda, you can install with:

conda install -c alubbock pygraphviz
