我尝试使用graphviz
我使用的是Windows 10，PyCharm，Anaconda3，Python3.6
我尝试了一些关于安装graphviz和pygraphviz
First solution (doesn't solve the following errors):
1a. conda update matplotlib
1b. conda install -c anaconda graphviz
1c. conda install -c anaconda python-graphviz
Second solution (doesn't solve the following errors):
1 . Download and install graphviz-2.38.msi from
https://graphviz.gitlab.io/_pages/Download/Download_windows.html
2 . Set the path variable
(a) Control Panel > System and Security > System > Advanced System Settings > Environment Variables > Path > Edit
(b) add 'C:\Program Files (x86)\Graphviz2.38\bin'
3. run python -m pip install graphviz
4. run python -m pip install git+https://github.com/pygraphviz/pygraphviz.git --install-option="--include-path=/usr/include/graphviz" --install-option="--library-path=/usr/lib/graphviz/"
然后返回

但它会返回这些错误：

答案 0 :(得分：0)
我试图使用Pycharm安装，但得到：ModuleNotFoundError：没有名为'graphviz'的模块
刚刚运行：pip install graphviz 并固定了它
