(solved)RPi.GIO install failing pip corrupt?

Hi
tried to install RPi.GPIO but failed.

having python 2.7.13
and osmc : 4.19.55-6-osmc

sudo pip install rpi.gpio
Traceback (most recent call last):
File “/usr/local/bin/pip”, line 6, in
from pip._internal import main
ImportError: No module named _internal

checking pip.
sudo apt-get install python-pip

python-pip is already the newest version (9.0.1-2+deb9u1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Followed already: but this does not solve it .

looks like pip is not correct?

thanks for hints

Update: Alright, so I figured I was missing a python module called setuptools, so I installed it just now by sudo apt-get install python-setuptools . Right after I run sudo pip install rpi.gpio "
