如何在导入igraph时解决AttributeError？

Question

当我在项目中导入igraph包时,我得到一个AttributeError.这只发生在项目目录中:

[12:34][~]$ python2
Python 2.7.1 (r271:86832, Apr 15 2011, 12:09:10) 
[GCC 4.5.2 20110127 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import igraph
>>> 

[12:34][~]$ cd projectdir/
[12:34][projectdir]$ python2
Python 2.7.1 (r271:86832, Apr 15 2011, 12:09:10) 
[GCC 4.5.2 20110127 (prerelease)] 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 "/usr/lib/python2.7/site-packages/igraph/__init__.py", line 42, in <module>
    import gzip
  File "/usr/lib/python2.7/gzip.py", line 36, in <module>
    class GzipFile(io.BufferedIOBase):
AttributeError: 'module' object has no attribute 'BufferedIOBase'
>>>

项目目录中没有文件igraph.py:

[12:34][projectdir]$ ls -alR | grep igraph | wc -l
0

而且没有循环进口.

我该如何解决这个错误？

最有可能的,有一个模块io中~/projectdir或项目配置的路径之一.igraph导入的gzip模块以

import io

并期望内置的io模块,而不是你的项目.查找io目录或io.py或io.pyc.它还可以帮助仔细检查可能包含命名模块的sys.path任何其他目录(可能在其外~/projectdir)io.
