Import error: you must be root

I'm trying to use the keyboard library in python 3 but continue to get an import error. I ran the program in windows in Thonny and It worked fine but I cant run it in the pi. I tried running it both as root and with sudo command with the same results. Below is the code as well as the error.

import keyboard
import time

x=0

while True:
    print (x)
    x=x+1
    print ("Press t to end program")
    if keyboard.is_pressed('t'):
        break
    else:
        pass

print("I'm done")

Output

0

Very late response, but I had your same problem. Just found a solution. You have to be root to run this program! The "Gotcha" comes, however, to how you installed the keyboard library...

Make sure when you installed the keyboard library that you did a:

sudo pip3 install keyboard

I did not do a sudo and first time I installed it. So what happened is that:

1) you try to run the program without being root

the library DOES exist, but you are not root so you get the issue you got

2) you try to run teh program as root

But pip3 did not install it for a root user, so you get a "keyboard not recognized".

hope this helped.

On raspberry pi open terminal and go the code folder. Type below command

sudo python filename.py

that's it. If you try to run code with IDLE it will always show this root related error.

Another solution. One thing is we want to run the IDLE as root permission.

Open terminal. Type command 'sudo idle'. It will create a new window of IDLE which has permission of root.
Now on that opened IDLE window FILE-> Open -> open the python file that you want to run.
Now go to Run-> Run Module.

Now the python script will run with root permission, as by typing 'sudo idle' we run the IDLE with root permissions.
