Answer 1

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.

Answer 2

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

import serial

instead of

from serial import serial

Answer 3

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

Answer 4

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)

Answer 5

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.

Answer 6

I found that the below worked when I encountered this same problem:

from serial import *
