Python ImportError: cannot import name itemgetter

问题

Python 2.7.5 (default, Sep 12 2013, 12:43:04) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/urllib.py", line 33, in <module>
  from urlparse import urljoin as basejoin
File "/usr/local/lib/python2.7/urlparse.py", line 118, in <module>
  from collections import namedtuple
File "/usr/local/lib/python2.7/collections.py", line 9, in <module>
  from operator import itemgetter as _itemgetter, eq as _eq
ImportError: cannot import name itemgetter

This issue occurs when I run import urllib. Python verison is 2.7. Does is Python's version problem ? Could someone tell me how to fix it ? Thanks a lot !

回答1:

You have a file called operator.py in the current directory, so import operator is picking up your module and not the Python standard library module operator.

You should rename your file to not conflict with Python's standard library.
