You are installing it from the wrong channel.您从错误的渠道安装它。 Do:
做:
conda install -c conda-forge pygraphviz
Updates: Windows更新:Windows
It appears that there are challenges installing pygraphviz on windows.在 windows 上安装 pygraphviz 似乎存在挑战。 Assuming that graphiz is installe and added to Path, which is a separate program (not python library) these solution might work
假设 graphiz 已安装并添加到 Path 中,这是一个单独的程序(不是 python 库),这些解决方案可能有效
# Tom Hanks’ answer
conda install graphviz pygraphviz -c alubbock
See SO answers Installing Pygraphviz on Windows请参阅 SO 答案在 Windows 上安装 Pygraphviz
"conda install graphviz pygraphviz -c alubbock" worked for me, within an Anaconda cme.exe terminal (and several failed attempts with other approaches). “conda install graphviz pygraphviz -c alubbock”在 Anaconda cme.exe 终端中为我工作(以及使用其他方法的几次失败尝试)。 Elsewhere I had also been told to install a C+ compiler, which I did within Visual Studio.
在其他地方,我也被告知安装 C+ 编译器,我在 Visual Studio 中完成了这项工作。 But maybe you can try without installing the C+ compiler
但也许你可以尝试不安装 C+ 编译器
