py2exe不导入os模块？

Question

所以，基本上，我正在尝试将我的Python 2.7脚本变成EXE。这是我的setup.py：

from distutils.core import setup
import py2exe
import os

setup(
     options = {
          "py2exe":{
              "includes": ["os"]
              }
          },  
  name = "Anansi CalcPad",
  version = "0.35",
  description = "Anansi CalcPad is a three-tiered application that provides a journal, calculator, and news aggregator in one.",
  author = "Cody Dostal",
  author_email = "cody@seafiresoftware.org",
  url = "http://seafiresoftware.org/wordpress/anansi-calcpad/",
  windows = ["AnansiCalc.py"],
  )

如果存在缩进问题，则是由StackOverflow上的错误副本引起的，而不是代码中的。

这是错误：

Traceback (most recent call last):
  File "AnansiCalc.py", line 3, in <module>
ImportError: No module named os

有什么问题？
