I just copied and pasted the code and I don't really get this error message. The pyserial package was installed using PIP. What am I doing wrong?
do you have a file named serial.py?

not that I'm aware of... If I knew how to check the PIP packages I would.
no, I mean your own file serial.py in the same folder as the script you run. That would shadow the package you import. It's a common newbie mistake.

No. I don't. Is that the problem?
If you had - this could be cause of the problem. Unfortunately, now I don't have another idea
Can you do
import os
import serial
print(os.path.abspath(serial.__file__))
Can you run pip list | grep serial? If you install the serial package after the pyserial package, that can mask it.

I figured it out. Apparently I had another PIP package called "serial" installed which totally doesn't do what I want. Anybody know how to handle with conflicts like that?
