I downloaded the WebIOPi-0.6.0.tar.gz from the web and extract it and ran the setup.sh. After installation when i run sudo webiopi it displays this.. 

ralph@ralph-desktop:~$ sudo webiopi
Traceback (most recent call last): 
  File "/usr/lib/python3.5/runpy.py", line 174, in _run_module_as_main mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/usr/lib/python3.5/runpy.py", line 133, in _get_module_details return _get_module_details(pkg_main_name, error)
  File "/usr/lib/python3.5/runpy.py", line 109, in _get_module_details __import__(pkg_name)
  File "/usr/local/lib/python3.5/dist-packages/WebIOPi-0.6.0-py3.5-linux-armv7l.egg/webiopi/__init__.py", line 17, in <module>
  import _webiopi.GPIO as GPIO
_webiopi.GPIO.SetupException: This module can only be run on a Raspberry Pi!

what seems to be wrong? i tried to reinstall it but the problem is still present.

Edited

I ran the code by @Codino and got this result.

During handling of the above exception, another exception occurred:

Because the version you've used was not compatible. Try this.

$ wget http://sourceforge.net/projects/webiopi/files/WebIOPi-0.7.1.tar.gz
$ tar xvzf WebIOPi-0.7.1.tar.gz
$ cd WebIOPi-0.7.1
$ wget https://raw.githubusercontent.com/doublebind/raspi/master/webiopi-pi2bplus.patch
$ patch -p1 -i webiopi-pi2bplus.patch
$ sudo ./setup.sh

  • still error, please see the edited part, i've copied the result there when i ran the commands – Ralph Jul 20 '16 at 19:13
  • does samba server have anything to do with this? or does having a NAS in the raspberry pi be the possible reason? because i'm running a NAS server with my pi – Ralph Jul 20 '16 at 19:15
  • @Ralph yes, it could be. I recommend disable other server service to test WebIOPi first, then if it works well you could use them all by changing the port of the servers. – Van Tr Jul 21 '16 at 05:03
  • hey i tried changing to port to 8000 and it doesn't give me the error on top but when i go to http://raspi-ip:8001 it just displays a blank screen – Ralph Jul 22 '16 at 18:09
