I have installed RPi.GPIO by:
pip install RPi.GPIO and ran the install script again, but get this:

Traceback (most recent call last):
   File "", line 1, in 
   File
"/home/rob/.local/lib/python2.7/site-packages/RPi/GPIO/__init__.py",
line 23, in 
     from RPi._GPIO import *
RuntimeError: This module can only be run on a Raspberry Pi!
./instal.sh: line 15: [: =: unary operator expected
I2C Pins detected as 1
I2C Library setup for this revision of Raspberry Pi, if you change
revision a modification will be required to i2c_lib.py
Now overwriting modules & blacklist. This will enable i2c Pins
Should be now all finished.  Please press any key to now reboot. After
rebooting run
'sudo python demo_lcd.py' from this directory


I am trying to get this to work or run on a Pi Zero with a 16x2 lcd
screen, and although the python demo_lcd.py script runs but for some
reason it isn't activating the lcd screen
