Your Graphviz installation could not be found.
1) You don't have Graphviz installed:
Install Graphviz (http://graphviz.org)
2) Your Graphviz package might incomplete.
Install the binary development subpackage (e.g. libgraphviz-dev or similar.)
3) You are using Windows
There are no PyGraphviz binary packages for Windows but you might be
able to build it from this source. See
http://networkx.lanl.gov/pygraphviz/reference/faq.html
If you think your installation is correct you will need to manually
change the include_dirs and library_dirs variables in setup.py to
point to the correct locations of your graphviz installation.
The current setting of library_dirs and include_dirs is:
library_dirs=None
include_dirs=None
error: Error locating graphviz.

如何解决问题。
【问题讨论】：
你应该先安装 Graphviz。 (lebienv) ➜ lebi git:(master) ✗ brew list graphviz 【参考方案1】：按照错误消息中的建议设置 library_dirs 和 include_dirs 对我有用。 This article 显示如何设置它们。但是，首先要确保 pygraphviz 已实际安装。
pip install --install-option="--include-path=/usr/local/include/graphviz/" --install-option="--library-path=/usr/local/lib/graphviz" pygraphviz
【讨论】：
pip install --install-option="--include-path=/usr/local/include/graphviz/" --install-option="--library-path=/usr/local /lib/graphviz" pygraphviz 谢谢@jamjar 您应该将此作为额外答案发布。我节省了大约 10 个小时的尝试时间。【参考方案2】：你试过了吗
pip install git+git://github.com/pygraphviz/pygraphviz.git
正如issue 中所建议的那样？
