Using WebSocket on WP7605

I would like to run WebSocket (using python ).
So, I can not find pip or apt-get command.
I tried install pip ↓,

curl -kL https://bootstrap.pypa.io/pip/2.7/get-pip.py | python
but I cannnot installed because of ImportError.
ImportError: No module named pkgutil

How I can use WebSocket?

you need to rebuild yocto to include the required library:

But I don’t see there is official recipe for python websocket.
