Enthought Canopy 在 OS X 上安装 igraph

Question

OS X：10.9.3 机盖：1.4.0（64 位）

我尝试使用多种方法安装 python-igraph 均未成功。以下是最近的两次尝试。任何建议将不胜感激。

首先，使用 Canopy 中的 setup.py：

%cd "/Users/user/Downloads/python-igraph-0.7"
/Users/user/Downloads/python-igraph-0.7
run -i setup.py install
running install
running bdist_egg
running egg_info
writing python_igraph.egg-info/PKG-INFO
writing top-level names to python_igraph.egg-info/top_level.txt
writing dependency_links to python_igraph.egg-info/dependency_links.txt
reading manifest file 'python_igraph.egg-info/SOURCES.txt'
reading manifest template 'MANIFEST.in'
writing manifest file 'python_igraph.egg-info/SOURCES.txt'
installing library code to build/bdist.macosx-10.6-x86_64/egg
running install_lib
running build_py
running build_ext
Cannot find the C core of igraph on this system using pkg-config.
We will now try to download and compile the C core from scratch.
Version number of the C core: 0.7
We will also try: 0.7.0

Version 0.7 of the C core of igraph is not found among the nightly builds.
Use the --c-core-version switch to try a different version.

Could not download and compile the C core of igraph.

WARNING: we were not able to detect where igraph is installed on
your machine (if it is installed at all). We will use the fallback
library and include pathss hardcoded in setup.py and hope that the
C core of igraph is installed there.

If the compilation fails and you are sure that igraph is installed
on your machine, adjust the following two variables in setup.py
accordingly and try again:

- LIBIGRAPH_FALLBACK_INCLUDE_DIRS
- LIBIGRAPH_FALLBACK_LIBRARY_DIRS

编辑：添加当前 ImportError txt：

>>> import igraph
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named igraph
>>> exit()

Answer 1

我终于想通了。非常感谢 +Tamas 展示了极大的耐心。当前的磁盘映像文件不够健壮，无法处理 Enthought Canopy 发行版的唯一安装位置。我在尝试 igraph 安装的顺序上也犯了几个错误。正确的过程首先需要更新 igraph 的 C 核心，然后使用 相应的 源代码使用 [% python setup.py install] 进行 python-igraph 安装。
