ImportError: No module named suds

问题:

Having trouble with py2exe importing the suds module, and narrowed it down to the following:

>>> imp.find_module('suds', sys.path)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named suds

However, a simple import works fine:

>>> import suds
>>> suds.__version__
'0.4'

Here is my sys.path, which shows suds at 'C:\Python27\lib\site-packages\suds-0.4-py2.7.egg':

>>> pprint.pprint(sys.path)

Why isn't imp.find_module locating the suds module?

回答1:

Extracted the suds egg at:

C:\Python27\lib\site-packages\suds-0.4-py2.7.egg

and created C:\Python27\lib\site-packages\suds directory that contains source files. Module is now found:

>>> imp.find_module('suds')
(None, 'C:\\Python27\\lib\\site-packages\\suds', ('', '', 5))

py2exe build completes successfully. It appears that imp.find_module requires directory with module source files to exist, an egg file is not recognized.
