我无法在 mac 10.6 上导入 igraph

我在我的 mac 中安装了 python 的 igraph 但无法导入它。首先我安装了 C 核心库，然后我继续安装 python，方法是：

python setup.py build
python setup.py install

一切似乎都工作正常，但我无法从 python shell 导入 igraph。澄清一下，我不在 igraph 源代码的文件夹内。我收到此错误：

import igraph
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build/bdist.macosx-10.3-fat/egg/igraph/__init__.py", line 30, in <module>

  File "build/bdist.macosx-10.3-fat/egg/igraph/core.py", line 7, in <module>
  File "build/bdist.macosx-10.3-fat/egg/igraph/core.py", line 6, in __bootstrap__
ImportError: dlopen(/Users/*****/.python-eggs/python_igraph-0.5.4-py2.7-macosx-10.3-fat.egg-tmp/igraph/core.so, 2): Symbol not found: _igraph_vector_destroy
  Referenced from: /Users/*****/.python-eggs/python_igraph-0.5.4-py2.7-macosx-10.3-fat.egg-tmp/igraph/core.so
  Expected in: dynamic lookup

我将文件夹名称替换为 *，所以不要考虑它。

我在操作系统 10.6.7 上运行 python 2.7。因此没有可用的 igraph 预编译版本（仅限 2.5 和 2.6）。这个错误和我运行的python版本有关系吗？如果可以的话，我该如何解决这个问题？

I installed igraph for python in my mac but I can't import it. First I installed C core library, then I proceeded with the instalation for python, by doing:

python setup.py build
python setup.py install

Everything seemed to work fine but I can't import igraph from python shell. Just to clear up, I'm not inside igraph source code's folder. And I got this error:

import igraph
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build/bdist.macosx-10.3-fat/egg/igraph/__init__.py", line 30, in <module>

  File "build/bdist.macosx-10.3-fat/egg/igraph/core.py", line 7, in <module>
  File "build/bdist.macosx-10.3-fat/egg/igraph/core.py", line 6, in __bootstrap__
ImportError: dlopen(/Users/*****/.python-eggs/python_igraph-0.5.4-py2.7-macosx-10.3-fat.egg-tmp/igraph/core.so, 2): Symbol not found: _igraph_vector_destroy
  Referenced from: /Users/*****/.python-eggs/python_igraph-0.5.4-py2.7-macosx-10.3-fat.egg-tmp/igraph/core.so
  Expected in: dynamic lookup

I replaced my folder's name for *, so don't consider it.

I'm running python 2.7 over OS 10.6.7. So there's no pre-compiled version of igraph avaliable (2.5 and 2.6 only). Has this error anything to do with the python version I'm running?
If possible, how can I work this out?

我认为问题在于 igraph 安装在 /usr/local/lib/libigraph.dylib 中，但是当 Python 尝试加载 igraph 模块的 C 核心时，链接器找不到它，因为 /usr/local/lib 不在 Mac OS X 中的默认库路径上。（至少我这么认为）。

首先，请检查 libigraph.dylib 是否确实在 /usr/local/lib 中 - 它应该在那里。之后，试试这个：

DYLD_LIBRARY_PATH=/usr/local/lib python -m igraph.test.__init__

这应该指示链接器在 /usr/local/lib 以及默认位置中查找，然后使用整个 igraph 测试套件运行 Python。

I think the problem is that igraph is installed in /usr/local/lib/libigraph.dylib, but the linker cannot find it when Python tries to load the C core of the igraph module because /usr/local/lib is not on the default library path in Mac OS X. (At least I think so).

First, please check whether libigraph.dylib is really in /usr/local/lib - it should be there. After that, try this:

DYLD_LIBRARY_PATH=/usr/local/lib python -m igraph.test.__init__

This should instruct the linker to look around in /usr/local/lib as well as the default places, and then run Python with the entire igraph test suite.
