error on "pip install rns"

[f4gbv]

does someone have an idea ?

I tried with pip3. I tried to install only cryptography with pip/pip3.

it seems that some versions are not compatible?

though I did an apt update / upgrade

thanks in advance

here is the beginning of error :

Try upgrading pip and related modules first:

python3 -m pip install --upgrade pip setuptools wheel

Then follow the Raspberry Pi install instructions from the Reticulum manual, which installs cryptography using apt not pip:

# Install dependencies
sudo apt install python3 python3-pip python3-cryptography python3-pyserial

# Install Reticulum
pip3 install rns --break-system-packages

https://markqvist.github.io/Reticulum/manual/gettingstartedfast.html#raspberry-pi

Typically you should not use sudo with pip related commands. One reason is that your pip packages will install for the root user instead of your user which causes issues later.

many thanks for your answer

I tried your advice but it failed:

1. python3 -m pip install --upgrade pip setuptools wheel
   ----> ok

2. sudo apt install python3 python3-pip python3-cryptography python3-serial
   ----> ok

3. pip install rns --break-system-packages
   ----> launched but failed with error : "my environnement version does'nt match
   :'( , despite of --break option)

So I decided to install "rnspure" , as explained in manual.
It workes fine.

I've already installed rNode on my pi4B, and it went fast and well.

this pi is a pi zéro first version without wifi, has someone already tried rns on such a pi?

best regards
