我在 macOS Mojave 10.14.1 上安装 pygraphviz 时遇到问题。我使用的Python版本是3.6.7。
执行命令时pip install pygraphviz，我收到以下冗长的错误消息：

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
provide path to graphviz include and library. For example:
pip install pygraphviz --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"
The current setting of library_dirs and include_dirs is:
library_dirs=None
include_dirs=None
error: Error locating graphviz.

有人可以帮我吗？谢谢！
I applied the suggestion of @hoefling: xcode-select --install, and then try pip3 install pygraphviz. An error is still existing like the following pictures:
该问题已通过使用以下命令完成：
pip install pygraphviz --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"
