Following the getting started guide fails for RPi IoT Kit due to pip failure on atcom apparently

Looking forward to getting started with sixfab, but ran into a bit of an unexpected roadblock.

Following it’s instructions attempting to install atcom via pip:
sudo pip3 install --no-cache-dir -U atcom

results in:

Any idea what this could be?

Python version: Python 3.7.3
Pip version: pip 18.1
cat /etc/os-release:

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"

Thanks for any insight that can be provided

I’ll update if I manage to find a fix. In the mean time if there’s anything else I can add to help you help me. Let me know

I was able to fix this by upgrading pip.

For anyone interested, pip issue: TypeError: expected string or bytes-like object - When doing pip install, or upgrading pip. · Issue #11343 · pypa/pip · GitHub
And the fix:

curl https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py

sudo because the sixfab script uses sudo when installing atcom
If you want to use the same version of pip without sudo then use the revised command:

curl https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
python3 get-pip.py

But you’d be better off using a virtualenv for libs that don’t require sudo
