IronPython cannot import module os

So I have a basic ZIPPED IronPython (2.6 or 2.6.1) that I just unzip, start ipy.exe, type "import os" and hit enter. The following output happens:

Traceback (most recent 开发者_高级运维call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named os

It doesn't work even if I import clr first. What's it to be done ?

I've googled this issue but no relevant answer. The closest idea was this (which didn't work):

import clr
clr.AddReference("IronPython")
clr.AddReference("IronPython.Modules")
import os

Likely, the problem is not the in zip, but in os module location.

You need to have CPython installed and your script should be able to reach the CPython Lib directory. To get this you can either copy all the os necessary files under your Lib directory, or you can set the environment variable IRONPYTHONPATH to point to the Lib directory below CPython.

This must help:

import sys
sys.path.append("C:\\PythonXY\\Lib")
