'import site' failed; use -v for traceback

Hello everyone,
I am trying to develop application on WR31 and I got this issue when compiling this error.
ss507079>‘import site’ failed; use -v for traceback
‘import site’ failed; use -v for traceback
Traceback (most recent call last):
File “Test.py”, line 1, in
import socket
ImportError: No module named socket

I do not know what I did wrong accidentally. Can someone help me out ?
Thank you
