Luc - this worked for me on a 4GB pi4. You'll see I added the ssl library
as well as the rust compiler.
I added the --verbose flag to watch cryptography build since it takes a
'long' time (16 minutes) to build even on a pi4.
# needed for weewx
sudo apt-get install -y gcc
sudo apt-get install -y python3-dev
python3 -m pip install wheel --user
# needed for cryptography
sudo apt-get install -y rustc
sudo apt-get install -y libssl-dev
# this takes many minutes to complete
pip3 install --user cryptography --verbose
# finally - install weewx
python3 -m pip install weewx --user
I might add that you don't need to do the 'trust the weewx repo' steps from
your original post for pip installations.
