2.ImportError: DLL load failed: 找不到指定的模块。
—————————————————————————————————-
D:\Program Files\Python2.6>python
Python 2.6 (r26:66721, Oct  2 2008, 11:35:03) [MSC v.1500 32 bit (Intel)] on win32

D:\Program Files\Python2.6\lib\site-packages\MySQLdb\__init__.py:34: DeprecationWarning: the sets module is deprecated
  from sets import ImmutableSet
—————————————————————————————————-
解决方法：
1) file “__init__”, replace: 
 
from sets import ImmutableSet  
class DBAPISet(ImmutableSet):  
 
with  
 
class DBAPISet(frozenset) 
 
2) file “converters.py”, remove: 
 
from sets import BaseSet, Set 
 
3) file “converters.py”, change “Set” by “set” (IMPORTANT: only two places): 
 
line 48: return set([ i for i in s.split(',') if i ]) 
line 128: set: Set2Str,
