我不知道该怎么做但我真的需要将graphviz布局与networkx一起使用。
我是按照graphviz无法找到的安装过程的具体方式进行的：
找不到您的Graphviz安装。
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.
这是我的python版本：
(py3_testing) jespinozlt-osx:~ jespinoz$ python
Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 12:04:33)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
这是我的OS上的Mac版本：
(py3_testing) jespinozlt-osx:~ jespinoz$ sw_vers
ProductName: Mac OS X
ProductVersion: 10.11.6
BuildVersion: 15G1217
我确保已安装graphviz：
(py3_testing) jespinozlt-osx:~ jespinoz$ ls -l ~/anaconda/envs/py3_testing/include/| grep "graphviz"
drwxr-xr-x 29 jespinoz tigr 986 Jun 6 12:51 graphviz
(py3_testing) jespinozlt-osx:~ jespinoz$ ls -l ~/anaconda/envs/py3_testing/lib/| grep "graphviz"
drwxr-xr-x 18 jespinoz tigr 612 Jun 6 12:51 graphviz
现在，当我尝试通过pip安装时：
(py3_testing) jespinozlt-osx:~ jespinoz$ pip install pygraphviz --install-option="--include-path=~/anaconda/envs/py3_testing/include/graphviz/" --install-option="--library-path=~/anaconda/envs/py3_testing/lib/graphviz"

mxnet 1.1.0 has requirement numpy<=1.13.3, but you'll have numpy 1.14.2 which is incompatible.

使用以下命令行（您需要homebrew）：
brew install graphviz
