It seems to be saying it can't find Python.

I don't know if Python is available in Home Assistant.
Maybe this is something to raise in the HA forum?

But it might be worth trying at the command line npm config set python $(which python) and then try again to install the palette node[s].

[craigcurtin]

Pretty sure this is to do with NR 3.02 and Python 3 - i remember seeing something on this forum recently by the maintainer of the docker image and a proposed work around inside the image to do a link of the python executables to overcome it.

@jbudd

npm config set python $(which python)

no idea, where to write this sentence.
Anyway, thanks for answer.

[jbudd]

@jbudd

at the command line ...

If you don't understand what the command line is, probably you should do a bit of background reading on Linux. If not for this issue since @craigcurtin has pointed you to a possible work-around, it will be a sound investment.

[agino]

there is only add-on terminal. Do exist any other? How to run?
just type npm return error, cause it doesnt know it. Where should be located?

[craigcurtin]

Nope as you are running Node Red in a Container under Home Assistant your best bet is through (HACS) install portainer into Home Assistant.

THis will then allow you to easily get a command line interface in the docker container that houses Node Red

Craig

[jbudd]

Oh good grief, is that what Home Assistant looks like?
I'm completely out of my depth here. Give me RPiOS Lite any day!

Sorry @agino it's clear I can offer nothing more than my original suggestion of the HA forum.
But @craigcurtin seems to know what he's talking about.

[craigcurtin]

Yep thats just the front end editor menu rather than Dashboards etc created in it.

Craig

[agino]

I did install HACS.

what next?

[craigcurtin]

From within HACS you should be able to find Portainer and then install that - this will then let you see the containers you are running in HASSos - once you have done this you highligh the NR container and there is an option to open a console

Craig

[agino]

hmm, no idea what next. there is no portainer. only monitor docker, but i dont know even how to start it and what to look for.

[hardillb]

The real problem here is that the node-red-contrib-lgtv is broken and needs fixing.

Either it or more likely one of it's dependencies (bufferutil) needs updating to use python3.

So even if you do manage to get this to work you should raise and issue against that node.

p.s. Also running npm config set python $(which python) will not work as there is NO python binary anymore in the container, only python3

[craigcurtin]

OK you have two paths here - you can either read up on Docker and how to get a console into a Docker container - or do some searching on how to install Portainer in Home Assistant to enable management of Docker containers.
