Recently I had same error. Reason for that I came in thus post.

I have using spyder version 6, installed with flatpak, before I used spyder 5.4.2 (native of debian's repositories).

Was strange because an old script worked fine, then I thinked if proof the same script in Jupyter Notebook? and no problem! then I proof in Pyzo, zero problem, further I decided reinstall spyder 5.4.2, and surprise, it work:

import serial

puerto_serial = '/dev/ttyACM0'
baud_rate = 9600
timeout = 10
    
arduino = serial.Serial(puerto_serial, baud_rate, timeout=timeout)

My humble opinion, if is problem of IDE?

I wanted to use minimalmodbus and got the same error message as in the title of this post. What worked for me:

sudo apt install python-is-python3

Apparently there was some confusion between python 2 and 3 and python-is-python3 resolved it.

I was getting the same error, but what works for me was:

  1. uninstall serial : pip3 uninstall serial
  2. uninstall pyserial: pip3 uninstall pyserial
  3. reinstall a previous version of pyserial: pip3 install pyserial==3.3 (I had 3.5 version)

uninstalling python and pyserial package completely and then

installing python(python 3 in my case) back -

for all users and add Paths correctly

and then use

pip3 for installing pyserial

fixed all my issues

I installed serial library using "pip3 install serial" and get the same error even calling the library using "import serial". Then I found that if first UNINSTALL serial:

pip3 uninstall serial

and then install pyserial:

pip3 install pyserial

fixed the problem for python 3.

Looking at the documentation it looks like you only need to do

import serial

instead of

from serial import serial
