没有sudo不能在python中导入模块-Ubuntu 12.04

Question

自从我升级到ubuntu 12.04以来，我觉得这是一个新问题。

现在，如果我进入交互式外壳程序并导入urllib2类的标准模块，则会出现以下错误：

$ python
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 urllib2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/urllib2.py", line 94, in <module>
   import httplib
  File "/usr/lib/python2.7/httplib.py", line 79, in <module>
   import mimetools
  File "/usr/lib/python2.7/mimetools.py", line 6, in <module>
   import tempfile
  File "/usr/lib/python2.7/tempfile.py", line 34, in <module>
   from random import Random as _Random
  File "/usr/lib/python2.7/random.py", line 47, in <module>
   from os import urandom as _urandom
  ImportError: cannot import name urandom
Error in sys.excepthook:

    from apport.fileutils import likely_packaged, get_recent_crashes
  File "/usr/lib/python2.7/dist-packages/apport/__init__.py", line 1, in <module>
    from apport.report import Report
  File "/usr/lib/python2.7/dist-packages/apport/report.py", line 12, in <module>
    import subprocess, tempfile, os.path, urllib, re, pwd, grp, os
  File "/usr/lib/python2.7/tempfile.py", line 34, in <module>
    from random import Random as _Random
  File "/usr/lib/python2.7/random.py", line 47, in <module>
    from os import urandom as _urandom
    ImportError: cannot import name urandom

Original exception was:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/urllib2.py", line 94, in <module>
    import httplib
  File "/usr/lib/python2.7/httplib.py", line 79, in <module>
    import mimetools
  File "/usr/lib/python2.7/mimetools.py", line 6, in <module>
    import tempfile
  File "/usr/lib/python2.7/tempfile.py", line 34, in <module>
    from random import Random as _Random
   File "/usr/lib/python2.7/random.py", line 47, in <module>
from os import urandom as _urandom
ImportError: cannot import name urandom
>>>

如果我在进入交互式shell之前运行sudo，那么一切都很好，它会导入而不会抛出异常。

我不想只对整个/usr/lib/python2.7目录进行chmod 755修改，那么我该怎么做才能使事情以更明智的方式更平稳地运行呢？

使用虚拟机。 这将为您提供一个干净的环境，不受以前的安装的影响。
