我在Linux上使用PyDev编写代码时遇到了这个奇怪的错误.即使像这样的简单代码也会产生错误

print 'Hello World'

而错误就在这里

True
Traceback (most recent call last):
  File "/usr/lib/python2.7/site.py", line 62, in <module>
    import os
  File "/usr/lib/python2.7/os.py", line 398, in <module>
    import UserDict
  File "/usr/lib/python2.7/UserDict.py", line 83, in <module>
    import _abcoll
  File "/usr/lib/python2.7/_abcoll.py", line 11, in <module>
    from abc import ABCMeta, abstractmethod
ImportError: cannot import name ABCMeta

我的模块名为sample.py.请帮我.谢谢
