west flash fail

[ziv123]

hello Nordic

i am using nrf52840 with zephyr ncs

unfortunatly i used this command "pamac install downgrade" at one point

since then i can not use 'west flash --erase'

the result for that command is :

augury_app git:(zh1_bist) ✗ west flash --erase

pkg_resources.DistributionNotFound: The 'west==0.10.1' distribution was not found and is required by the application
➜  augury_app git:(zh1_bist) ✗ 

i have tried the following:

pip3 install --user cmake west
and in ncs directory:
 pip3 install --user -r zephyr/scripts/requirements.txt
 pip3 install --user -r nrf/scripts/requirements.txt
 pip3 install --user -r bootloader/mcuboot/scripts/requirements.txt

and still the same 

any ideas ???

hope to read from you soon 

best regards

Hi,

 

This line indicates that it is something in your system requiring this specific version of west:

pkg_resources.DistributionNotFound: The 'west==0.10.1' distribution was not found and is required by the application

 

Have you tried building and running other samples to see if you get the same behavior there? Could it be enough to remove your build folder and reconfigure?

 

Kind regards,

Håkon

hi 

ok, what actually solved the issue for me was downgrading my nrfx command tool from 10.15 to 10.12.2

i did it by downloading that version to my download dir and run the following command

sudo pacman -U ~/Downloads/nrf5x-command-line-tools-10.12.2-2-x86_64.pkg.tar.zst

thanks

best regards

Ziv
