导入igraph时出错：ImportError：无法导入名称community_to_membership

Question

我不确定这是否已被回答，但我找不到任何与我的错误有关的内容，所以我想我会发一个问题。

我在Linux上运行，我使用pip install python-igraph下载了igraph包，并确保它是由Tamas Nepusz提供的python-igraph-0.7.1包。

当我尝试做import igraph时，我收到以下错误：

~$ python
Python 2.7.12 (default, Dec  4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import igraph
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/lashen/.local/lib/python2.7/site-packages/igraph/__init__.py", line 34, in <module>
    from igraph._igraph import *

    from igraph.cut import *

    from igraph.clustering import VertexClustering

    from igraph import community_to_membership
ImportError: cannot import name community_to_membership

我不知道如何修复此导入错误。我是否错误地安装了igraph？好像我得到了正确的包裹......

~$ pip show python-igraph

我已经尝试导入igraph的单个子模块，但无济于事。所有子模块导入（例如import igraph.cut，import igraph._igraph）都会导致相同的错误。

为什么会出现此导入错误？感谢任何帮助，谢谢！

您需要先安装sudo apt-get install libigraph0-dev，然后才能通过pip install python-igraph --user安装igraph
