有人成功地在Windows10 64位上安装了pygraphviz吗？我尝试了蟒蛇3.5 64位和32位，但没有成功。
下面是我在win10 64位上使用python 3.5 32位得到的错误
python -m pip install pygraphviz --install-option="--include-path=C:\Program Files (x86)\Graphviz2.38\include" --install-option="--library-path=C:\Program Files (x86)\Graphviz2.38\lib"
错误：

我想这和graphviz以32位连接的事实有关吧？
注意-我尝试了所有在互联网上找到的pygraphviz二进制文件（anaconda，internet），但没有一个在win10 64位上工作…如果你有任何工作（我是说你真的测试过它），我也会很高兴…
最佳答案
从这里开始阅读
https://github.com/pygraphviz/pygraphviz/issues/58
在该页的底部有一个指向GitHub中x64 zip文件的链接
解包，为您的x64文件创建一个coresponding program files文件夹，并将它们放在那里。
然后用这个安装
pip install --global-option=build_ext --global-option="-IC:\Program Files\Graphviz2.38\include" --global-option="-LC:\Program Files\Graphviz2.38\lib\release\lib" pygraphviz
