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 

Hello

Did you do the install python dependencies step?  https://docs.zephyrproject.org/latest/getting_started/index.html#install-python-dependencies

Best regards

Serafin

Hmm, that shouldn't be needed if the Python dependencies were installed
correctly.

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

Right, but that doesn’t require you to set PYTHONPATH, but to add that dotlocal folder to your PATH.
See here:

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?

Great!

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.

Comments appreciated.

I’m with Charles. I had to add this to my .bashrc

export PATH=~/.local/bin:$PATH

Once I did this everything is good.

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).

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.

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

Is this still a problem for you? It looks like you are using the zephyr
SDK as your toolchain. I'm not sure why a newlib file is being linked in
for hello_world, though. That sample shouldn't be using newlib.

Great!

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.

Comments appreciated.

I’m with Charles. I had to add this to my .bashrc

export PATH=~/.local/bin:$PATH

Once I did this everything is good.

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

Not my experience. The last time I installed the dependencies went into a

What distro are you using? Did you try running python3 -m site as

described below to debug?

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

correctly.

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
