Pour les utilisateurs de Fedora:

  1. yum list available graphviz*
  2. sélectionnez le package approprié pour votre distribution Fedora
  3. Sudo yum install 'graphviz-devel.x86_64'
  4. pip install pygraphviz

Sur macOS, je l'ai fait avec,

$ brew install graphviz
$ Sudo pip install pygraphviz

Pour CentOS. Comme graphviz-devel est nécessaire pour résoudre ce problème, vous devez l'installer avec yum. Pour ce faire, vous devez ajouter un repo où le package est disponible. Dans mon cas, Atomic le repo a bien fonctionné.

wget -q -O - http://www.atomicorp.com/installers/atomic | sh

Cela va ajouter des repos atomiques, puis

Sudo yum install graphviz-devel

Et vous devriez pouvoir effectuer

pip install pygraphviz
