在Windows上安装pygraphviz

Question

在我的Windows 7 Ultimate 64bit上安装最新的graphviz(2.26.3)之后,我收到以下错误:

C:> easy_install pygraphviz搜索pygraphviz阅读 http://pypi.python.org/simple/pygraphviz/ 阅读 http://networkx.lanl.gov/pygraphviz 阅读 http://networkx.lanl.gov/wiki/download 阅读 http://networkx.lanl.gov/download/pygraphviz 阅读 http://sourceforge.net/project/showfiles.php?group_id=122233&package_id=161979 阅读 http://networkx.lanl.gov/download最佳匹配:pygraphviz 1.1 .dev1947正在下载 http://networkx.lanl.gov/download/pygraphviz/pygraphviz-1.1.dev1947.tar.gz 处理pygraphviz-1.1.dev1947.tar.gz运行pygraphviz-1.1.dev1947\setup.py -q bdist_egg - -dist-dir c:\ users\jonathan\appdata\local\temp\easy_install-apywwk\pygraphviz-1.1.dev1947\egg-dist-tmp-nvd0pa尝试pkg-config无法找到pkg-config尝试dotneato-config失败找到dotneato-config

找不到您的graphviz安装.

在不完整的二进制包graphviz-dev或graphviz-devel缺失的情况下,graphviz包是否缺失？).

如果您认为安装正确,则需要手动更改setup.py中的include_path和library_path变量,以指向graphviz安装的正确位置.

library_path和include_path的当前设置是:library_path = None include_path = None

错误:无

有任何想法如何解决这个问题？
这似乎与这里描述的问题不同.
有没有人成功在Windows上安装pygraphviz？怎么样？

Answer 1

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

1)下载pygraphviz来源

2)编辑setup.py以将路径改为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libs链接对我不起作用.

3)跑 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

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