Pygraphviz install error

Hi, after several tries, I’m getting the following error trying to install pygraphviz in Windows 10:

Not able to install pygraphviz #156

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 FilesGraphviz2.38include» —global-option=»-LC:Program FilesGraphviz2.38libreleaselib» pygraphviz

The text was updated successfully, but these errors were encountered:

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
Python37-32Scripts>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

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

I have no idea how to apply that patch on Windows

Unhelpful Error Message on Install #192

First i installed graphviz using pacman

While installing pygraphviz via pip

I got the following error message

The text was updated successfully, but these errors were encountered:

I performed a full system upgrade, rebooted and re-installed both and it happened to fix the issue

however I came across a similar error when I install pygraphviz before graphviz
and I think that should give a more helpful error message such as
Error Occurred! Make sure you have graphviz installed first

Installing pygraphviz without having graphviz previously installed gives

This problem does occur when graphviz is not installed first. But it also occurs whenever it can’t find the libcgraph package. That can happen when graphviz is installed somewhere that PKG_CONFIG_PATH doesn’t help find. So, the error message given is reasonable: it suggests that you add the location of ‘libcgraph.pc’ to the PKG_CONFIG_PATH. In doing so, you will determine that libcgraph.pc is not installed and thus that graphviz has not been installed. Putting a more descriptive error message is beyond the scope of pygraphviz as far as I know.
