Pip install pygraphviz fails: Failed building wheel for pygraphviz
Question:
I have troubles installing pygraphviz on macOS 10.10.5. I have a fully functional installation of Python 2.7.x, and I’d like to run the test example of queueing-tool, which requires installing pygraphviz using pip.
When executing the command pip install pygraphviz, I get the following lengthy error message:

I am unsure about how to address the above error. All other Python packages, such as numpy or networkx, were straightforward to install. Any help would be greatly appreciated. Thanks a lot in advance.
Answers:
The comment by Andrew brought me on the right path. Thank you for that.
It turns out that a detailed solution for installing pygraphviz on macOS is already available on stackoverflow, see this solution by teut.
Try this :
sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config
or the following might be needed if you’re using Python 3:
sudo apt-get install python3-dev graphviz libgraphviz-dev pkg-config
then
sudo pip install pygraphviz
Basically you need to download graphviz first using brew:
brew install graphviz
pip install graphviz
pip install pygraphviz
You can also try using pip3 in place of pip just in case there is Python’s version issue. Hope it helps.
This worked for me (M1 Mac)
brew install graphviz
python -m pip install
--global-option=build_ext
--global-option="-I$(brew --prefix graphviz)/include/"
--global-option="-L$(brew --prefix graphviz)/lib/"
pygraphviz
I have troubles installing pygraphviz on macOS 10.10.5. I have a fully functional installation of Python 2.7.x, and I’d like to run the test example of queueing-tool, which requires installing pygraphviz using pip.

Package libcgraph was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcgraph.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcgraph' found

I am unsure about how to address the above error. All other Python packages, such as numpy or networkx, were straightforward to install. Any help would be greatly appreciated. Thanks a lot in advance.
The comment by Andrew brought me on the right path. Thank you for that.
It turns out that a detailed solution for installing pygraphviz on macOS is already available on stackoverflow, see this solution by teut.
Try this :
sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config
or the following might be needed if you’re using Python 3:
sudo apt-get install python3-dev graphviz libgraphviz-dev pkg-config
then
sudo pip install pygraphviz
Basically you need to download graphviz first using brew:
brew install graphviz
pip install graphviz
pip install pygraphviz
You can also try using pip3 in place of pip just in case there is Python’s version issue. Hope it helps.
This worked for me (M1 Mac)
brew install graphviz
python -m pip install
--global-option=build_ext
--global-option="-I$(brew --prefix graphviz)/include/"
--global-option="-L$(brew --prefix graphviz)/lib/"
pygraphviz
