python 'module' 对象没有属性 'compile'

Question

[root@proxy-001 scripts]# python
Python 2.6.6 (r266:84292, Dec  7 2011, 20:48:22)
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
   >>> import MySQLdb
   >>> from MySQLdb import cursors
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 16, in <module>
        insert_values= re.compile(restr)
    AttributeError: 'module' object has no attribute 'compile'

有什么想法吗？

同样的错误:

    insert_values= re.compile(restr)
AttributeError: 'module' object has no attribute 'compile'

编辑:/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py 添加:

print re
print dir(re)
insert_values= re.compile(restr)

Answer 1

这很奇怪。您的 Python 路径中是否有一个名为“re.py”的模块正在隐藏“真正的”re 模块？

更新:好的，根据你的编辑，我现在确定你有一个 re.py 模块，它正在遮蔽真实的模块，如果我正确读取路径，它就在你所在的目录中从调用程序!您是否编写了具有一个“modify_url”函数的 re.py 模块？

无论如何，找到 re.py —— 它可能在你的脚本目录中 —— 并将它重命名为其他名称。
