注意：以下任何帖子均未涉及此问题：1、2、3。

目的是安装 PyGraphviz 以使用 python-weka-wrapper 提供的可视化工具。我只是无法安装 PyGraphviz。以下是我从pip尝试时遇到的错误

$ sudo pip install git+git://github.com/pygraphviz/pygraphviz.git

Graphviz 是在 MacPorts 的帮助下安装的。在上面的结果中，它的路径是明确的

include_dirs=/opt/local/include/graphviz
library_dirs=/opt/local/lib

graphviz/cgraph.h 也存在。那么安装出了什么问题。

我在网上尝试了所有方法，但似乎没有任何效果。这是我尝试过的完整列表。

从 git 安装：

sudo pip install git+git://github.com/pygraphviz/pygraphviz.git
从包源的 setup.py 安装：

sudo python setup.py install
使用包含和库路径沿着 win 命令行安装：

sudo python setup.py install --include-path=/opt/local/include/graphviz --library-path=/opt/local/lib/graphviz

每一个都抛出相同的错误。

我该怎么办？

【问题讨论】：

你是怎么解决这个问题的？我已经尝试了所有这些选项，但没有任何效果？

标签： python macos installation package pygraphviz

【解决方案1】：

尝试改用：include_dirs=/opt/local/include

【讨论】：

这将受益于显示实际的命令行。是否带有include_dirs=xxx pip install ...，即临时环境变量？是--include_dirs 标志吗？谁知道？

【解决方案2】：

这对我来说很好用：

pip install --global-option=build_ext --global-option="-I/opt/local/include/" --global-option="-L/opt/local/lib" PyGraphviz

参考：python pip specify a library directory and an include directory

【讨论】：

也为我工作。直接开箱即用，无需大惊小怪。请记住，OP 在 macports 上，因此 Brew 看起来会有所不同，即可能是 /usr/local。

【解决方案3】：

这对我来说很好用：

pip install --install-option="--include-path=/usr/local/include/" --install-option="--library-path=/usr/local/lib/" pygraphviz

参考：PyGraphvizをmacOSにインストールする

【讨论】：

这看起来像是基于 Brew 的安装，而 OP 询问的是 macports。请注意 /usr/local 与 /opt/local 的不同之处。路径。如果您使用 Brew，可能会起作用，但 whitecoffee 与端口相关的答案对我有用。
