I had this same problem. My solution was to export PYTHONPATH to include

installing all the dependencies, it is installed on your system
Hmm, that shouldn't be needed if the Python dependencies were installed

Everything went well with your manuals but when I try this one

west build -b reel_board samples/hello_world

(in my case west build -b qemu_x86 samples/hello_world )

The error which can't find pykwalify comes up like below.
Based on your screenshot, it looks like you are running on Linux, so you
should have installed west using "pip3 install --user west", which it
looks like you did:

-- Found west: /home/jaeminy.choi/.local/bin/west

If so, then pykwalify should have been installed too, because west
declares it as a dependency to pip:

$ pip3 show west | grep Requires:
Requires: colorama, PyYAML, pykwalify, configobj, setuptools

So as Allen said, if you have west but it can't import pykwalify, there
is a problem with the Python path. But you shouldn't need to set
PYTHONPATH; pip and Python's USER_BASE should take care of this for you.

First, you should check that pykwalify is installed, like this:

$ pip3 show -f pykwalify | grep Location:
Location: /home/foo/.local/lib/python3.6/site-packages

If that doesn't work, reinstall west with pip3 to make sure you get it.

Second, run "python3 -m site". The output should contain the pykwalify
installation directory in sys.path. Something like this:

$ python3 -m site
sys.path = [
USER_BASE: '/home/foo/.local' (exists)
USER_SITE: '/home/foo/.local/lib/python3.6/site-packages' (exists)

Make sure:

1. USER_SITE is the directory where pykwalify was installed
3. sys.path contains the directory where pykwalify was installed

For more details, check:

I've googled it to solve the problem but i ended up here.
By the way, for the future, please consider cutting and pasting text
instead of using screenshots of your terminal window as discussed in

It makes it easier for others to google your exact error message.

Can I have some advices?
Hope this helps.


(All programs I should install are beyond minimum version and I skipped
set up a toolchain step because I set up the Zephyr SDK toolchains)
