First uninstall serial withsudo pip uninstall serial (thank you so much Ali!)

Then, ifimport serial does not work anymore: usesudo pip install pyserial. This will install the correct serial module for the RP.

• BaxMode's answer helped me. (but I cannot up vote it yet due to lack of reputation here) I pip installed serial, when I should have installed pyserial. (I'm using Windows with Anaconda, soconda install pyserial worked for me.)

• This works, but I'll add a bit more explanation. There are two different packages that provide a module called 'serial' to the python system. One is called 'serial' by pip, and that is a serialization library (nothing to do with serial ports). The other is called 'pyserial' by pip, and that is the one that does serial port handling on the system. It is a very unfortunate name conflict in the python ecosystem, that I've hit myself. Uninstalling the serialization module and making sure the serial port handling module is installed should work.

I had the same issue and I tried all the suggestions I encountered on the internet, but non has worked for me. Finally, I was able to solve the problem by uninstalling theserial package fromusr/local/lib that had the issue for some reason. you can uninstall this package bysudo pip uninstall serial.Here is what you can try:

• write this short piece of codeimport serialprint(serial.__file__),.This outputs the path of the module being imported in your code.
• if the output is/usr/local/lib/pythonx.x/dist-packages/serial/__init__.py, then go ahead and uninstallserial. If it was/usr/lib/pythonx.x/dist-packages/serial/__init__.py, then you have another type of problem.
• repeat the 1st step after the uninstall and check that the output is the second one
• now try your code again

PS: you may need to usepip3 instead ofpip in case you are using python3.

Hope this helps

have a look atthis page.I have the same issue because I have installed serial instead of pyserial.To check, enterdir(serial)If you do not see the Serial method, you have the wrong package

Yes this topic is one year old but i wanted to share the solution that worked for me for those who might need it anyway

As Ali said, try to locate your program using the following from terminal :

 sudo python3 import serial

print(serial.__file__)--> Copy

CTRL+D #(to get out of python)

sudo python3-->paste/__init__.py

Activating__init__.py will say to your program "ok i'm going to use Serial from python3". My problem was that my python3 program was using Serial from python 2.7

Other solution: remove other python versions
