python - 导入错误:没有名为 suds 的模块

Question

在 py2exe 导入 suds 模块时遇到问题，并将其缩小为以下问题:

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

但是，一个简单的导入就可以正常工作:

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

这是我的 sys.path，它在“C:\Python27\lib\site-packages\suds-0.4-py2.7.egg”处显示泡沫:

>>> pprint.pprint(sys.path)
['',

确认2.7下安装了py2exe:

为什么 imp.find_module 没有找到 suds 模块？

Answer 1

在以下位置提取泡沫鸡蛋:

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

并创建了包含源文件的 C:\Python27\lib\site-packages\suds 目录。现在找到模块:

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

py2exe 构建成功完成。看来 imp.find_module 需要包含模块源文件的目录存在，无法识别 egg 文件。
