I had this web application running from a Raspberry Pi 2 with no problem using WebIOPi, I recently acquired a Raspberry Pi 3, and I wanted to use the same application on it, using a 7'' screen.
I installed WebIOPi with no problem, and copied the same html files and the script I had in the other Pi. But when I run WebIOPi I get this error:
File "/home/pi/myproject/python/script.py", line 8, in < module> GPIO = webiopi.GPIO AttributeError: 'module' object has no attribute 'GPIO'
I saw another question that is similar, but it's for a Pi 2 and it didn't work in my case.
What can I do?
