Python install failure Pi3

Having problems getting the python SDK to install:
Rasp Pi 3
Raspbian jessie based openplotter image -
http://www.sailoog.com/openplotter

From the terminal, seemed to work OK til almost the end -

Cleaning up…
Command /usr/bin/python -c “import setuptools, tokenize;file=‘/tmp/pip-build-YcvOPs/python-wifi/setup.py’;exec(compile(getattr(tokenize, ‘open’, open)(file).read().replace(‘\r\n’, ‘\n’), file, ‘exec’))” install --record /tmp/pip-Eu04f3-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip-build-YcvOPs/python-wifi
Storing debug log for failure in /root/.pip/pip.log

And the log -

Suspect the raspbian image might be causing the problems, any ideas?

EDIT - Cancel that cry for help, removed /usr/local/man file and it seemed to install OK . Ta

Error is coming from pip. Follow these instructions to remedy:

sudo apt-get remove python-pip python3-pip
sudo wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

Same issue in Nova python installer broken? - #5 by benstr

Hi. I’m sorry but, mine said
ERROR: This script does not work on Python 2.7. The minimum supported Python version is 3.6. Please use https://bootstrap.pypa.io/pip/2.7get-pip.py instead.
