For CentOS. As graphviz-devel is required to fix this issue, you will need to install it with yum. To do this you are required to add repo's where package is available. In my case Atomicrepos worked fine.

对于 CentOS。由于需要使用 graphviz-devel 来解决此问题，因此您需要使用 yum 安装它。为此，您需要在包可用的地方添加 repo。就我而言，Atomicrepos 工作正常。

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

This will add atomic repos, then

这将添加原子回购，然后

sudo yum install graphviz-devel

And you should be able to perform

你应该能够执行

pip install pygraphviz
