buildprog.py not working

[PeterRasmussen]

Hey

I try to follow the guide here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.4.1/nrf/applications/nrf5340_audio/README.html#building-and-running

when i use the scrip approach i get the following error:

i have installed latest sdk 2.4.1 and it works if i build it manually as described in the steps below.

Hi,

The python module "encodings" is missing. Looking at the paths there seems to be an issue with your environment variables (assuming you installed via the toolchain manager), so you are using the wrong python install. Can you try to open the terminal from the toolchain manager? That should set the PATHs correctly.

[PeterRasmussen]

i have sourced the env.sh generated from the toolchain manager.

i will try to run it from a terminal opened from the toolchain manager

[PeterRasmussen]

That results in the same error

[Einar Thorsrud]

I see. That is odd. There is a problem here with python though, the specific error is with loading encodings, which should be there. I also notice that the executable that is used is /usr/bin/python, where it should have been using the one from the toolchain. Is that also the case after you opened the window from the toolchain manager? Can you show the output from the script in that case?
