python3.6 networkx使用pygraphviz绘图报TypeError

报错如下:

查了下使用的networkx版本,networkx (1.11),networkx在2.0版本才开始支持3.6,怀疑版本问题

NetworkX 2.0

Release date: TBD

Support for Python 3.6 added, drop support for Python 3.3.

升级完后发现还是报错,查看报错信息,觉得还是跟pygraphviz有关系,升级到最新的1.4rc1,升级进要指定一些参数.
默认–library-path获取到的为None,我手工指定路径

1	pip install pygraphviz==1.4rc1 --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib64/graphviz/

再次执行.成功出图.
