SES Blinky build error

[denis]

I'm trying to build the blinky zephyr sample for nRF Connect SDK and get the following failure:

If I try to install the package it can't seem to find, it appears it is already installed:

$ pip3 install pyyaml --user

Requirement already satisfied: pyyaml in /usr/local/lib/python3.8/site-packages (5.3.1)

I can build other zephyr projects from the command line ok.

Any idea what might be the issue here?

Do you have several versions of python installed? It may be that zephyr/scripts/dts/edtlib.py is looking somewhere else for the package. Take a look at your environment variables, and remove the ones you're not using.

Could you try to run the following commands:

cd <sourcecode_root>\ncs
pip3 install -r zephyr\scripts\requirements.txt
pip3 install -r nrf\scripts\requirements.txt
pip3 install -r bootloader\mcuboot\scripts\requirements.txt

You could also try to install NCS through the Toolchain Manager (TM), and open SES from TM?

Please tell me if you encounter any issues with this approach (which you may do, since the TM is experimental for macOS), and I will help get it to work with the Manual approach.

Best regards,

Simon
