在Windows，Python 2.6上安装PygraphViz

Question

有人在Windows上成功安装了PygraphViz吗？

由于没有Windows的正式发行版，因此我尝试自己构建它，但无法编译。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

任何帮助，将不胜感激！

Answer 1

这是在Python 2.7中对我有用的。我认为它在Python 2.6中应该类似地工作。前提条件：安装mingw32（如果使用的话，包含在pythonxy
distrib中）

1）下载pygraphviz来源

2）编辑setup.py以将路径更改为

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libs链接对我不起作用。

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）将结果从刚刚构建的lib.win32-2.7（称为的单个子文件夹）复制pygraphviz到Python的site-packages文件夹中

请享用！
