ImportError：没有名为functools的模块（Windows 10）

Question

在Win10 Python2.7中运行Python Batch时出现以下错误。以前在Win7中正在运行同一批处理。

C:/Users/Chris/.platformio/penv/lib/python2.7/site.py", line 703, in 
main()
C:/Users/Chris/.platformio/penv/lib/python2.7/site.py", line 692, in main
aliasmbcs()
C:/Users/Chris/.platformio/penv/lib/python2.7/site.py", line 515, in aliasmbcs
import locale, codecs
C:\Users\Chris.platformio\penv\lib\python2.7/locale.py", line 17, in 
import functools

ImportError: No module named functools

checked Python27 has Functool installed.

请帮忙.. !!
