我正在尝试在我的 64 位 Windows 7 SP1 安装上安装 pygraphviz。python setup.py install
通过更正文件的以下行,我能够使通常的命令正常工作setup.py
:
include_dirs = r"C:\Program Files (x86)\Graphviz2.38\include"
library_dirs = r"C:\Program Files (x86)\Graphviz2.38\lib\release\lib"
但是,当我尝试导入它时,我收到以下错误:
Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pygraphviz
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pygraphviz\__init__.py", line 58, in <module>
from .agraph import AGraph, Node, Edge, Attribute, ItemAttribute
File "pygraphviz\agraph.py", line 26, in <module>
from . import graphviz as gv

_graphviz = swig_import_helper()
File "pygraphviz\graphviz.py", line 20, in swig_import_helper
import _graphviz
ImportError: No module named _graphviz
这很令人费解,因为安装 pygraphviz 的目录确实包含一个_graphviz.pyd
文件。如果我去那个目录并尝试导入它,我会得到一个不同的 ImportError:
C:\Python27\Lib\site-packages\pygraphviz>python
Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win32

>>> import _graphviz
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: DLL load failed: The specified module could not be found.
据我所知,_graphviz.pyd 文件似乎编译不正确(我使用的是 mingw32,已相应地编辑了我的 distutils.cfg 文件)。我无法从其他 pygraphviz 用户那里找到这个问题的任何其他实例。我究竟做错了什么?
