I need Help - pip install socket.IO-client -failed

Volumio Development
1

Hello everyone,

I have a little problem there. I am currently trying to use these instructions https://github.com/edmw/volumio-diy to have a USB RFID reader talk to Volumio.

I had already successfully set this up at the beginning of the year.

Unfortunately my SD card broke two weeks ago.

Now I fail at the point where I have to set up a virtual environment with python, namely when installing the socketIO client.

Volumio version: 2909

Python. 3.4

(volumio-hid) volumio @ lalabox: ~ $ python3 -m pip install socketIO-client

Storing debug log for failure in /home/volumio/.pip/pip.log

I already googled but can’t find a working solution. I’m not a programmer and I try to muddle my way through it. : conf:

Does anyone have an idea or does anyone know the problem?

Switch to Buster beta - that might be an easier solution.

Current (2.878+) images are partly stretch and partly buster, causing quite some chaos with dependency management.

Said and done. Volumio Version 3.083 installed.
But now it seems to disagree with the Python syntax. I now get when starting the service. The following message is displayed in journalctl.

Can someone here help me with troubleshooting? Apparently there are problems with line 303 in HID.py.
In a task with asyncio.async …

task = asyncio.async (read_events (hid))
         task.add_done_callback (partial (read_events_done, device = hid))
         return task

Hmm, I would ask the author of the script for help…

Good luck! :slight_smile:

Looks like you need to update it to work with python 3.6+ code, as async is now a reserved word.
Or a low effort way if you are already using pyenv is to run it on Py3.6

I had already tried to contact the author of the Git article … unfortunately without success.

ok, unfortunately I am an absolute beginner when it comes to programming. So, does that mean that the word async is used somehow differently. So in the script no longer works. Yes, an update of the script would be cool. Unfortunately, I first have to understand Python in general (better from programming). But thank you for your answers.

Does anyone know whether there are already other solutions with a USB RFID reader, perhaps even as a plug-in?

So far I have only found one NFC reader plugin. But that addresses a wired RFC reader with 13.56 MHz. That probably also runs over the SPI interface.
No idea. Man, I wish I could understand the script better … :wink:

You could try posting here –

Or use pyenv to install 3.6

curl https://pyenv.run | bash
exec $SHELL
pyenv install 3.6
pyenv global system 3.6

And then go ahead with the previous stuff… Perhaps it is best to start forma a fresh image…

Hi,
I have now got the reader to work. I upgraded to Python 3.5.2 following these instructions Python 3 - #4 by Chris_Martini and then set up the environment with it.
The HID service is now running and recognizing the RFID cards. :tada:

@ashthespy Thanks again for your help. :+1:
