Installation error with node-red-contrib-solace

I'm a node-red newbie, would someone please try install node-red-contrib-solace from the palette to see if it's broken or is it just me?

Thanks in advance!

Did you edit the settings.js file and add the items it tells you to? (

however the node hasn't been updated in 5 years so it is quite possible it has been abandoned

Yep, I edited settings.js. I think this node was loading in a previous node-red install - that's why I am wondering whether others are having issues with it or whether maybe my new install (new version too) is screwed up somehow?

I just ran the install via the CLI and it installed fine. One thing I notice is you are on node.js v14.3.0 while I am using v12.13.0.

Can you downgrade node.js and see if it will install?

Thanks for giving it a try, that's encouraging! I'll see if I can figure out how to downgrade to v12.13.0. Would you mind sharing what you did in the CLI to get successful install - what directory you were in/ what options you specified etc - or was it just npm install node-red-contrib-solace?

It seems to have worked in the CLI for me too - but the node-red web interface isn't happy with something and the nodes don't appear on the palette for use :frowning:


I wonder if it has anything to do with node-red v1 doing away with the input and output groups in palette?
from the instructions:

Point your browser to http://localhost:1880

You should see orange solace input and output nodes in the pallet on the left side of the screen.

  • input
  • output

The nodes show up for me

This version of NR is running on my Mac, let me see what one of my Pi's shows.

Thanks for all your help so far!

What version of NR are you on?

interesting, on my Pi I get this at startup

the big clue is Error: Cannot find module '/usr/lib/node_modules/node-red/red/red' on the pi.

I've opened an issue in GitHub about incase you want to see if the author will reply (and hopefully fix it :grin:)

That looks like it's from here in solace.js:

// get the global settings so we can check log level for solace
var settings = require(process.env.NODE_RED_HOME+"/red/red").settings;

Interestingly, the log level is something you are instructed to set in the settings.js file specified in installation docs. I'm going to see what happens if I edit to hard code the path to that file :smiley:

Thanks very much.

It seems the same issue as was found here:

good spot :+1:, I've just added that to the issue
