无法与cygwin运行pexect

在Cygwin提示下执行pexpect示例文件时出现以下错误。 谁能帮忙?

Administrator@INDSQA2253 /cygdrive/c/Python26/Tools/pexpect-2.1/examples $ python ssh_session.py Traceback (most recent call last): File "ssh_session.py", line 7, in <module> from pexpect import * File "c:\Python26\lib\site-packages\pexpect.py", line 83, in <module> Pexpect is intended for UNIX-like operating systems.""") ImportError: No module named resource A critical module was not found. Probably this operating system does not support it. Pexpect is intended for UNIX-like operating systems. 

Pexpect可以使用从Cygwin调用的Windows for Python吗?

尝试从cygwin安装Python。 我的意思是cygwin的Python,可以安装
