Not able to install pygraphviz

[NikhilBansal21]

I am not able to install pygraphviz on windows 10 64 bit

I am running pip install --global-option=build_ext --global-option="-IC:\Program Files\Graphviz2.38\include" --global-option="-LC:\Program Files\Graphviz2.38\lib\release\lib" pygraphviz

Same thing with me... trying to use networkx which uses graphviz. I have graphviz installed. I have spent the whole day trying to resolve this.
OS: win 10
Py: 3.65

I have tried this
Python37-32\Scripts>pip install git+https://github.com/pygraphviz/pygraphviz.git --install-option="--include-path=C:/Program Files (x86)/Graphviz2.38/include" --install-option="--library-path=C:/Program Files (x86)/Graphviz2.38/lib/release/lib"

Which solved the problems with the include and lib files but now I am getting this

graphviz_wrap.obj : error LNK2001: unresolved external symbol _PyIOBase_Type
build\lib.win32-3.7\pygraphviz_graphviz.cp37-win32.pyd : fatal error LNK1120: 1 unresolved externals
error: command 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\link.exe' failed with exit status 1120

The only reference to the above issue is a patch mentioned at the end of this thread

#74

I have no idea how to apply that patch on Windows

Look at my comment there:

About the comment above, just replace the files from tar.gz by the raw fles of Kagami@fe442dc commit.

Hello

I have the same problem.
I installed graphviz using pip install
I have installed pygraphviz using winpython control center because using pip install I have an error

using winpython control center it's work and I can import the package in python;
But when I write G.layout()
I get the error

"Program neato not found in path."

What can I do?

Be careful... graphviz installed by pip is a python program. It is not GraphViz. You need GraphViz

[fraseg]

I managed to get past the include problem by changing setup.py to reference the paths to graphviz on my machine, for belt and braces I also set the PATH to point to both. Now it is failing on linking. @dshult please can you post to github a doc with instructions on how to install for windows 10 64 bit? I have spent all day trying to install I love the output so really want to use the module, please can you help?

conda install graphviz worked for me

Pygraphviz 1.7 was just released and it should be significantly more straightforward to install on Windows. Graphviz is still required, but Graphviz installation on Windows has also improved significantly since the OP - see the updated installation guide for details. Patching the source code should no longer be required to build+install pygraphviz on Windows.

If you run into problems installing pygraphviz on Windows, please open a new issue with updated info on how Graphviz was installed on your system.
