After installing the latest graphviz (2.26.3) on my Windows 7 Ultimate 64bit, I receive the following error:

您的graphviz安装无法 被发现.

Your graphviz installation could not be found.

缺少graphviz软件包 不完整(二进制包) graphviz-dev或graphviz-devel 失踪了吗?).

Either the graphviz package is missing on incomplete (binary packages graphviz-dev or graphviz-devel missing?).

如果您认为您的安装是 正确，您将需要手动 更改include_path并 setup.py中的library_path变量 指向您的正确位置 graphviz安装.

If you think your installation is correct you will need to manually change the include_path and library_path variables in setup.py to point to the correct locations of your graphviz installation.

library_path的当前设置 并且include_path是:library_path = None include_path =无

The current setting of library_path and include_path is: library_path=None include_path=None

错误:无

有什么想法要解决这个问题吗?
这似乎是与此处所述的问题不同的问题. br> 有没有人在Windows上成功安装pygraphviz?怎么样?

Any thoughts how to fix this?
This seems to be a different problem than the one described here.
Has anyone had success in installing pygraphviz on Windows? How?

推荐答案

这对我有用. 前提条件:安装mingw32(如果使用的话，包含在pythonxy distrib中)

Here's what worked for me. Precondition: Install mingw32 (included in pythonxy distrib if you're using it), Graphviz

1)下载pygraphviz来源

1) Download pygraphviz sources

2)编辑setup.py以将路径更改为类似

2) Edit setup.py to change paths to smth like

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.与库链接对我不起作用.

Note that it's \bin, not \lib. Linking with libs didn't work for me.

3)运行python setup.py build -c mingw32

第3步的结果

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

-lmsvcr90 -o build\lib.win32-2.7\pygraphviz\_graphviz.pyd

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

4) copy the result from the just built lib.win32-2.7 (single sub-folder called pygraphviz) into your Python's site-packages folder

享受！
