Getting "python3" to work

Hello. I am using my Pixy2 with my RaspberryPi for my school project. I’m trying to run my script but it is only able to run when I use “sudo python pixyexample.py.” However, I want to able to run it using “sudo python3 pixyexample.py” since my other devices only work with that prompt. I’ve already tried running build_all.sh and still no luck. Any help is appreciated. Here is what I get when I type “sudo python3 pixyexample.py.”

During handling of the above exception, another exception occurred:

Hello,
Please try rebuilding (run build_all.sh) and see if it reports any errors so we can narrow things down.
