问题描述
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 (r271:86832,2011年4月15日,12:09:10)
[GCC 4.5.2 20110127(预发行)] on linux2
输入help,copyright,credits或license 了解更多信息。
>>> import igraph
>>>
[12:34] [〜] $ cd projectdir /
[12:34] [projectdir] $ python2

输入help,copyright,credits或license以获取更多信息。
>>> import igraph
Traceback(最近一次调用最后一次):
文件< stdin>,第1行,< module>
文件/usr/lib/python2.7/site-packages/igraph/__init__.py,第42行,< module>
import gzip
文件/usr/lib/python2.7/gzip.py,第36行,< module>
class GzipFile(io.BufferedIOBase):
AttributeError:'module'对象没有属性'BufferedIOBase'
>>>
项目目录中没有文件igraph.py:
[12:34] [projectdir] $ ls -alR | grep igraph | wc -l
0
并且没有循环导入。
如何解决此错误?
最有可能的是,模块 io
在〜/ projectdir
或项目配置的其中一个路径中。 igraph导入的gzip模块以
import io
$ p $开头p>
并期待内置的io模块,而不是你的项目。查找
io
目录,或io.py
或io.pyc
。对于可能包含的任何其他目录(可能在〜/ projectdir
之外),它还可以帮助仔细检查sys.path
模块名为io
。When I import the igraph package in my project, I get an AttributeError. This only happens in the project directory:
[12:34][~]$ 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' >>>
There is no file igraph.py in the project directory:
[12:34][projectdir]$ ls -alR | grep igraph | wc -l 0
And there are no circular imports.
How can I solve this error?
解决方案Most likely, there is a module
io
in~/projectdir
or one of the paths the project configures. The gzip module imported by igraph starts withimport io
and expect the built-in io module, not your project's one. Look for an
io
directory, orio.py
orio.pyc
. It can also help to scrutinizesys.path
for any other directories (maybe outside of~/projectdir
) that might contain modules namedio
