poetry install hang

[nothingtodowu]

Hi pybricks team,

Thanks for all the efforts on pybricks! It is truly great!
I am new to Pybricks and this is the first time I try to compile code.
When I follow this, https://github.com/pybricks/pybricks-micropython/blob/master/CONTRIBUTING.md
My setup just hang there after I run "poetry install"
Anything I forgot for this issue? Thanks a lot.
Here is the log:

max@max-Default-string:~/pybricks-micropython$ poetry install

Sometimes poetry can take a really long time to resolve package dependencies. What Python version are you using? How long did you actually wait?

[dlech]

Python 3.10 should be fine.

And I should have noticed this before, but if it is getting to the install part, then the dependency resolution is done.

This (https://python-poetry.org/docs/repositories#debugging-issues) suggests running poetry with the --no-cache and -vvv options for troubleshooting.

Hi dlech,

I found the issue. My server is Ubuntu 20.04, which default python3 is python 3.8.4. Even I install python 3.10.14, python3 still link to 3.8.4. Then poetry just hang there. Can I use python 3.84 for build? Or any idea to change python3 to python3.10.14? I try several ways but all failed to install potery at my ubuntu 20.04.

[dlech]

You can type poetry env use python3.10 to use the different Python version, then continue with poetry install.

Thanks a lot. After I re-install Ubuntu 22.04, then everything is ok. I just got another issue when I run "make primehub". Below is the error message. Where can I find this "arm-none-eabi-gcc"? Thanska lot.

Hi Dlech,
I fixed issue with this link. Now I can build primehub image. Thanks a lot.

Hi Dlech, Now I can build image for primehub and download image now. May I know how to get this branch to latest master and build image? I try with "git branch -a | grep bluetooth" but can't find this branch. Thanks a lot.

Hi Lechner,

Thanks a lot. Is there anyway for Windows to program code? Or must use Ubuntu?

[dlech]

Compiling the Pybricks firmware probably only works on Linux currently, but everything else should be working cross-platform.

[nothingtodowu]

I try with this command "poetry run pybricksdev run usb run_wro.py" at Ubuntu 22.04 with spike prime hub which download usb enable firmware. Here is the error messages I got. Why it show "Could not find hub"? I already connect hub with the spike prime hub.

USB is not yet supported. The command poetry run pybricksdev run usb my_script.py is an outdated command that has nothing to do with this unfortunately.

run_wro.py

I would not recommend attempting to use USB for competitions at this stage. It is just not ready for that.

So backing up a few steps... Is USB absolutely needed for your case? Bluetooth is allowed in WRO as far as I know, at least according to the global organizers when I recently asked. It might be worth checking the rules of your local competitions.

[nothingtodowu]

Thanks a lot. Then I use bluetooth for now. Hope your USB official support can be released earlier.

Hi Lechner,

Sometime when I compile code I got this errors. How to recover when this issue happen? Thanks a lot.

This issue happen when I install and run VS Code at Ubuntu.

[dlech]

I don't see any error. It looks like a successful build to me. No output files were updated probably because they were built already and no source files were modified.

[nothingtodowu]

Got it

Hi Lechner,

Sorry, another issue. When I download firmware.zip at Ubuntu, chrome, I got this error. What need I do for Ubuntu download firmware? Thanks a lot.

An unexpected error occurred. Please consider reporting this so we can make a better error message.

[dlech]

Do you have the proper udev rules installed?

[nothingtodowu]

How to install this udev rules? My setup is Ubuntu 22.04

There is a link in Pybricks Code to the instructions.
