在Python 2.7中导入urllib或urllib2失败，出现ImportError: cannot import name iskeyword

Question

我在我的Python 2.6或Python 2.7环境中，无法导入urllib或urllib2这两个模块。

Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53) 
[GCC 4.5.2] 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/lib/python2.7/urllib.py", line 30, in <module>
    from urlparse import urljoin as basejoin
  File "/usr/lib/python2.7/urlparse.py", line 110, in <module>
    from collections import namedtuple
  File "/usr/lib/python2.7/collections.py", line 10, in <module>
    from keyword import iskeyword as _iskeyword
ImportError: cannot import name iskeyword

我在网上搜索“无法导入名称iskeyword”也找不到答案。

可能是有一些导入冲突。你在工作区里有没有叫 keyword 的模块？试试下面的代码：

>>> import keyword
>>> dir(keyword)
