error setup exception: no access to /dev/mem - Raspberry Pi Forums

hii everyone,
newbie , followed adafruit's instructions , made simple ledblinky project
start raspberry pi shows error
"error setup exception: no access /dev/mem"
pls pls pls me pls

in advanced

being able access /dev/mem privileged function, potentially quite risky.

in order program needs "root" or "super-user" powers (but doesn't need wear underpants on outside;-) ).

way use "sudo" command in front of program name on command line.

so, assuming trying run program

code: select all

python ledblinky.py 

need use

code: select all

sudo python ledblinky.py 

instead. instructions should have mentioned this.
