Hello.
This is Jaemin from Samsung Electronics and we are trying to set the environment up for Zephyr with https://docs.zephyrproject.org/latest/getting_started/index.html.
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.

I've googled it to solve the problem but i ended up here.
Can I have some advices?
(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)
Thanks,
Jaemin

I had this same problem. My solution was to export PYTHONPATH to include the directory containing this module. If you went through the instructions, installing all the dependencies, it is installed on your system somewhere.

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 = [ '/usr/local/lib/python3.6', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/home/foo/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', ] USER_BASE: '/home/foo/.local' (exists) USER_SITE: '/home/foo/.local/lib/python3.6/site-packages' (exists) ENABLE_USER_SITE: True Make sure: 1. USER_SITE is the directory where pykwalify was installed 2. ENABLE_USER_SITE is True 3. sys.path contains the directory where pykwalify was installed For more details, check: https://docs.python.org/3/library/site.html#site.USER_BASE

Not my experience. The last time I installed the dependencies went into a dotlocal directory under the user account. Python couldn’t find them.

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 = [
'/usr/local/lib/python3.6',
'/usr/lib/python36.zip',
'/usr/lib/python3.6',
'/usr/lib/python3.6/lib-dynload',
'/home/foo/.local/lib/python3.6/site-packages',
'/usr/local/lib/python3.6/dist-packages',
'/usr/lib/python3/dist-packages',
]
USER_BASE: '/home/foo/.local' (exists)
USER_SITE: '/home/foo/.local/lib/python3.6/site-packages' (exists)
ENABLE_USER_SITE: True
Make sure:
1. USER_SITE is the directory where pykwalify was installed
2. ENABLE_USER_SITE is True
3. sys.path contains the directory where pykwalify was installed
For more details, check:
https://docs.python.org/3/library/site.html#site.USER_BASE

See here: https://docs.zephyrproject.org/latest/getting_started/index.html#pytho n-and-pip I don't think that's the issue here. Jaemin can run west, but west can't import pykwalify. That's not a PATH (environment variable) issue, but a sys.path (Python module search path) issue, I think, no? He mentioned dependencies going to a dotlocal directory in his home, so I assumed he meant that the executable couldn't be found (since this is a very common case). Instead it was a Python module, so you are right. This is indeed about PYTHONPATH and not PATH in any case.

Not my experience. The last time I installed the dependencies went into a dotlocal directory under the user account. Python couldn’t find them.

Hello.
This is Jaemin from Samsung Electronics and we are trying to set the environment up for Zephyr with https://docs.zephyrproject.org/latest/getting_started/index.html.
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 = [ '/usr/local/lib/python3.6', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/home/foo/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', ] USER_BASE: '/home/foo/.local' (exists) USER_SITE: '/home/foo/.local/lib/python3.6/site-packages' (exists) ENABLE_USER_SITE: True
Make sure:
1. USER_SITE is the directory where pykwalify was installed 2. ENABLE_USER_SITE is True 3. sys.path contains the directory where pykwalify was installed
For more details, check:
https://docs.python.org/3/library/site.html#site.USER_BASE
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
https://docs.zephyrproject.org/latest/guides/getting-help.html#use-cop y-paste
It makes it easier for others to google your exact error message.
Can I have some advices?
Hope this helps.

We’re working on an updated getting started guide that streamlines this setup process so some important steps such as updating the PATH are not missed (so easily). Check out https://github.com/zephyrproject-rtos/zephyr/pull/19123 and the build artifacts for the GSG here: https://builds.zephyrproject.org/zephyrproject-rtos/zephyr/19123/docs/getting_started/index.html FWIW, recent versions of pip3 install will warn you if ~/.local/bin (or wherever it installs packages with --user) are not on PATH, so hopefully this problem will become less common as time goes on.

That is a separate issue as described in the back and forth between Carles and I. Let's not confuse the PATH environment variable, which is used to locate the executable "west" file, with sys.path, which is the variable Python uses to locate importable modules. The latter can be augmented using the PYTHONPATH environment variable, but it should not be necessary if python and pip3 are configured properly (and using the default configuration for at least Ubuntu and Arch in my testing).

Jaemin Choi <jaeminy.choi@...>
The import error is solved due to you guys. Thank you.
>>> 1. USER_SITE is the directory where pykwalify was installed
>>> 2. ENABLE_USER_SITE is True
>>> 3. sys.path contains the directory where pykwalify was installed
These checklists should be added on the website I think.
I figured it out that USER_SITE wasn't the directory where pkywalify was installed.
To make them same, i reinstall python3 with this command
pip install python3 --user --force-reinstall
and also had to remove build directory to make it try to build new setting.
however, I faced another error when Im trying this same command.
west build -b reel_board samples/hello_world --pristine

FWIW, recent versions of pip3 install will warn you if ~/.local/bin
(or wherever it installs packages with --user) are not on PATH, so
hopefully this problem will become less common as time goes on.

That is a separate issue as described in the back and forth between
Carles and I.
Let's not confuse the PATH environment variable, which is used to locate
the executable "west" file, with sys.path, which is the variable
Python uses to locate importable modules. The latter can be augmented
using the PYTHONPATH environment variable, but it should not be
necessary if python and pip3 are configured properly (and using the
default configuration for at least Ubuntu and Arch in my testing).
Thanks,
Marti

Jaemin Choi <jaeminy.choi@samsung.com> writes: The import error is solved due to you guys. Thank you. Glad that part is resolved, sorry you're still (maybe) having problems.
1. USER_SITE is the directory where pykwalify was installed
2. ENABLE_USER_SITE is True
3. sys.path contains the directory where pykwalify was installed
These checklists should be added on the website I think.
I figured it out that USER_SITE wasn't the directory where pkywalify was installed.
To make them same, i reinstall python3 with this command
pip install python3 --user --force-reinstall
and also had to remove build directory to make it try to build new setting.
however, I faced another error when Im trying this same command.
west build -b reel_board samples/hello_world --pristine

Hello.
This is Jaemin from Samsung Electronics and we are trying to set the
environment up for Zephyr with
https://docs.zephyrproject.org/latest/getting_started/index.html.
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 = [
'/usr/local/lib/python3.6',
'/usr/lib/python36.zip',
'/usr/lib/python3.6',
'/usr/lib/python3.6/lib-dynload',
'/home/foo/.local/lib/python3.6/site-packages',
'/usr/local/lib/python3.6/dist-packages',
'/usr/lib/python3/dist-packages',
]
USER_BASE: '/home/foo/.local' (exists)
USER_SITE: '/home/foo/.local/lib/python3.6/site-packages' (exists)
ENABLE_USER_SITE: True
Make sure:
1. USER_SITE is the directory where pykwalify was installed
2. ENABLE_USER_SITE is True
3. sys.path contains the directory where pykwalify was installed
For more details, check:
https://docs.python.org/3/library/site.html#site.USER_BASE
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
https://docs.zephyrproject.org/latest/guides/getting-help.html#use-copy-paste
It makes it easier for others to google your exact error message.
Can I have some advices?
Hope this helps.
Thanks,
Marti
(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)
Thanks,
Jaemin
