can't access GPIO with python periphery library

[shenouda 0]

Hi I am new to this forum. I am trying to use python-periphery library to use the pins  on the board.

if I do :

from periphery import GPIO

gpio3 = GPIO(3,"in")

I get the following error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 1017, in _open
    with open("/sys/class/gpio/export", "w") as f_export:
PermissionError: [Errno 13] Permission denied: '/sys/class/gpio/export'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/linaro/Desktop/temp_hum.py", line 7, in <module>
    gpio3 = GPIO(3,"in")
  File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 999, in __init__
    self._open(line, direction)
  File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 1020, in _open
    raise GPIOError(e.errno, "Exporting GPIO: " + e.strerror)
periphery.gpio.GPIOError: [Errno 13] Exporting GPIO: Permission denied

 

Any Idea how to solve this?
