For those using poetry this might help

CFLAGS="-I$(brew --prefix graphviz)/include/ -L$(brew --prefix graphviz)/lib/" poetry install

This is the only command that worked for me on my M1 MacBook Pro (MacOS 14.2.1):

python3 -m pip install -U --no-cache-dir  \
        --config-settings="--global-option=build_ext" \
        --config-settings="--global-option=-I$(brew --prefix graphviz)/include/" \
        --config-settings="--global-option=-L$(brew --prefix graphviz)/lib/" \
        pygraphviz

I use mac m1, I fix this by this.

#install graphviz first
brew install graphviz

#check your graphviz path   
brew info graphviz

#change to your dir
export GRAPHVIZ_DIR="/usr/local/Cellar/graphviz/<VERSION>" #3.0.0 in my case

#finally run this 
pip install pygraphviz --global-option=build_ext --global-option="-I$GRAPHVIZ_DIR/include" --global-option="-L$GRAPHVIZ_DIR/lib"

On Ubuntu 14.04, there is a problem in auto detecting graphviz library and include files. If you follow the steps below probably you'll be safe.

1) sudo apt-get install graphviz libgraphviz-dev pkg-config python-pip
2) pip install pygraphviz --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"

On Mac OSX El Capitan, Bart Theeten's solution works but there are two things you need to be careful. Initially, make sure that you installed graphviz on your computer. You can use homebrew:

brew install graphviz

Other thing is to make sure you add the path of packages to PYTHONPATH

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages/

On Mac OSX, the following did the trick for me:

pip install graphviz
pip install cgraph
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig 
cd /usr/local/include/graphviz 
sudo ln -s . graphviz 
pip install pygraphviz

[As suggested, fixed typo from previously /urs/local/ to /usr/local/]

Under Ubuntu 15.10+ (ie 2015ish Debian), the quick and easy solution is:

sudo apt-get install python-pygraphviz

Any dependencies are properly pulled by apt.

Assuming that you're on Ubuntu please look at following steps

  1. sudo apt-get install graphviz libgraphviz-dev pkg-config
  2. Create and activate virtualenv if needed. The commands looks something like sudo apt-get install python-pip python-virtualenv
  3. Run pip install pygraphviz
  4. Run terminal and check by importing and see if it works

The quick and easy solution is:

sudo apt-get install -y python-pygraphviz

using pip will also work, but make sure you have graphviz, libgraphviz-dev, and pkg-config already installed.

sudo apt-get install -y graphviz libgraphviz-dev pkg-config python-pip
sudo pip install pygraphviz
