Doesn't support apt installed versions of node-red

[shanness]

I suspect this is because most of my NR modules are in /usr/lib? (Because I used apt to install it).
Here is the error I get.

{ Error: Cannot find module '../../../../../../../../home/craig/.node-red/node_modules/node-red-dashboard'

[yoiang]

Hmm, I'll have a look through and see if the module is doing anything unusual with its includes or dependencies. node-red-dashboard is a requirement of the module and it shouldn't have any hard declaration to look for the module in a specific relative folder.

[yoiang]

Hey @shanness, I haven't had a chance to reproduce the situation, any change or luck figuring this out?

[shanness]

Hey @yoiang, I don't really know nodejs or node-reds internals, but do have this in

craig@home:~/.node-red$ ls /home/craig/.node-red/node_modules/node-red-dashboard
CHANGELOG.md  Charts.md  config-fields.md  CONTRIBUTING.md  dist  fixfa.js  ISSUE_TEMPLATE.md  LICENSE  license.js  nodes  package.json  README.md  ui.js

And this in ~/.node-red/.config

  "node-red-dashboard": {
   "name": "node-red-dashboard",
   "version": "2.9.8",
   "local": true,
   "nodes": {
    "ui_base": {
     "name": "ui_base",
     "types": [
      "ui_base"
     ],
     "enabled": true,
     "local": true,
     "module": "node-red-dashboard",
     "file": "/home/craig/.node-red/node_modules/node-red-dashboard/nodes/ui_base.js"

The problem seems to be the resolver adding all the ../.. stuff at the start?

{ Error: Cannot find module '../../../../../../../../home/craig/.node-red/node_modules/node-red-dashboard'

As /home/craig/.node-red/node_modules/node-red-dashboard/ exists.

If I go into the dir for the file reporting the error above (/usr/lib/node_modules/node-red/red/runtime/nodes/registry/loader.js), then this works.

craig@home:/usr/lib/node_modules/node-red/red/runtime/nodes/registry$ ls ../../../../../../../../home/craig/.node-red/node_modules/node-red-dashboard
CHANGELOG.md  Charts.md  config-fields.md  CONTRIBUTING.md  dist  fixfa.js  ISSUE_TEMPLATE.md  LICENSE  license.js  nodes  package.json  README.md  ui.js

Does that help at all?

[yoiang]

Is there an entry in the .node-red/.config file for node-red-contrib-ui-led? What does that look like?

[shanness]

  "node-red-contrib-ui-led": {
   "name": "node-red-contrib-ui-led",
   "version": "0.1.1",
   "local": true,
   "nodes": {
    "led": {
     "name": "led",
     "types": [
      "led"
     ],
     "enabled": true,
     "local": true,
     "module": "node-red-contrib-ui-led",
     "file": "/home/craig/.node-red/node_modules/node-red-contrib-ui-led/led.js"
    }
   }
  },

I'm having this exact issue too. Does anyone have the fix?

[yoiang]

Folks in #30 who also installed via apt-install say that updating to the latest version of ui_led (0.2.3) and rebooting fixed it for them. I'm not sure why yet but give it a go!

[shanness]

Hey @yoiang , Nah, sorry, didn't fix it. And if anyone is going to try, delete any LED nodes first! I had to manually hack them out of my flows_home.json (couldn't restart after upgrade without removing the existing test LED node.

Still getting this

[yoiang]

Are you comfortable enough to be able to test a branch without changing anything else? I just pushed https://github.com/Adorkable/node-red-contrib-ui-led/tree/feature/issue8 with a little change to match other libraries scoping of some variables, and may have another idea if that doesn't help.

[shanness]

Hey @yoiang ,
I removed the existing UI installed version, and ran this
craig@home:~/.node-red$ npm install https://github.com/Adorkable/node-red-contrib-ui-led.git#feature/issue8
I restarted NR, then added the LED node to my flow and redeployed, and got the same issue.

Is that the right way to test it?

[yoiang]

Yes, I think that should have installed it properly, dang. You haven't run into this issue at all with any other Node-RED UI nodes either?

Have you raised this in the Node-RED dashboard github? They might know exactly what's going on, I'm at a loss. At some point I'm going to have to recreate your installation, in a container I think.

[shanness]

Hey,

Got the same problem with this other dashbord plugin, and just checked, pretty sure they are the only two UI/dashboard plugins I'm using.

node-red-hitachi/ui_list#7

Haven't rasied in on the dashboard github yet. Are there any other UI plugins you'd suggest I try? Happy to help find one that works?

[yoiang]

You can check here for more contrib-ui, however it's sounding more and more like an issue with node-red-dashboard or with node-red!

[shanness]

Ta, just confirmed getting the same issue with ui-level. And others have reported it too.

hotNipi/node-red-contrib-ui-level#7

I'll move up the line, and perhaps check on discord as the above issue suggests. If I find a solution, I'll update all 3 tickets.

Thanks for your help.

[yoiang]

Hey @shanness, any luck on this front? Or can you paste the thread following this issue so others can follow along?

[shanness]

Hey @yoiang, I haven't had time to do anything about this, and unlikely will any time soon, just too busy with other projects and this isn't pressing enough to chase ATM. Sorry about that.

[yoiang]

No worries! I'm going to close the issue now that it's most likely a Node-RED/Node-RED Dashboard issue. If you do follow up feel free to post the link here.
