在urllib2、re和base64上导入python 2.7时出错

Question

我有一个python文件，它在我的本地计算机上运行正常，但是在服务器python 2.7.9（默认值）[GCC 4.4.7 20120313（Red Hat 4.4.7-11）]上记录这些错误

SyntaxError: invalid syntax
Traceback (most recent call last):
  File "/home/<dir>/kb_log.py", line 8, in <module>
    import urllib2
  File "/usr/local/lib/python2.7/urllib2.py", line 92, in <module>
    import base64
  File "/usr/local/lib/python2.7/base64.py", line 8, in <module>
    import re
  File "/usr/local/lib/python2.7/re.py", line 105, in <module>
    import sre_compile
  File "/usr/local/lib/python2.7/sre_compile.py", line 62
    for t in _equivalences for i in t}

当我在服务器上启动pythonshell并导入urllib2时，没有出现错误
