AttributeError: module ‘serial’ has no attribute ‘SerialException’ – Python 3.5

Hi everyone,

A quick fix for an error I ran into while updating to Pyhton 3.5.2:

AttributeError: module 'serial' has no attribute 'SerialException'

I needed to add pyserial:

pi@raspberrypi:~/Desktop/piscripts/get-commands $ sudo pip3.5 install pyserial

Could not find a version that satisfied the requirement smbus/python3-smbus

Hi everyone,

I ran into a bit of an issue installing smbus on Python3.5. It looks like all you have to do is use smbus2:

pip3.5 install smbus2

Updating to Python 3.5.1 on RaspberryPi

Hi everyone,

Just a quick post on how to update to Python 3.5.1 the normal upgrade process isn’t working for you:


cd ~
wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz
tar -zxvf Python-3.5.1.tgz
cd Python-3.5.1
./configure && make && sudo make install

You may need to restart once this is complete. Run the following to confirm that the version is 3.5.1:

pi@raspberrypi:~ $ python3 --version
Python 3.5.1
