在Windows上安装PygraphViz,Python 2.6

Question

有人在Windows上成功安装了PygraphViz吗？

由于没有适用于Windows的正式版本,我正在尝试自己构建它,但它无法编译.我不是第一个来面对这个问题,但我无法找到答案.

这是控制台输出:

C:\Python26\Lib\site-packages\pygraphviz-0.99.1>c:\python26\python.exe setup.py
install
library_path=C:/Program Files/Graphviz2.26.3/lib/debug/dll
include_path=C:/Program Files/Graphviz2.26.3/include/graphviz
running install

任何帮助,将不胜感激!

我很欣赏这可能是一个过时的线程,但是要为目前正在使用这个墙的其他人更新它,Christoph Gohlke的非扩展软件包的非官方Windows二进制文件的安装程序刚刚为我工作..

以下是 Python 2.7 中对我有用的内容。我认为它在 Python 2.6 中应该类似地工作。前提条件：安装 mingw32（如果您使用它，则包含在 pythonxy distrib 中）、Graphviz

1）下载pygraphviz源码

2）编辑setup.py以更改路径，例如

library_path=r"c:\Program Files (x86)\Graphviz 2.28\bin"
include_path=r"c:\Program Files (x86)\Graphviz 2.28\include\graphviz"

请注意，它是 \bin，而不是 \lib。与库链接对我来说不起作用。

3）运行python setup.py build -c mingw32

步骤3的结果：

c:\Python27\Lib\site-packages\pygraphviz-1.1>python setup.py build -c mingw32
library_path=c:\Program Files (x86)\Graphviz 2.28\bin
include_path=c:\Program Files (x86)\Graphviz 2.28\include\graphviz
running build
running build_py

4) 将刚刚构建的 lib.win32-2.7 （名为 的单个子文件夹pygraphviz）中的结果复制到 Python 的 site-packages 文件夹中

享受！
