@BrutalBirdie Thank's for your answer.
I'm not so familiar with Cloudron installation.I have read the linked documentation.
'If you require a custom module that is not installed in /app/code/node_modules, please make a post in our forum.'
I would like to have following custom module installed in /app/code/node_modules:
n8n-nodes-ninox
And how i have to write the added line like for /app/data/env:
export NODE_FUNCTION_ALLOW_EXTERNAL=???
-
@BrutalBirdie does the community nodes install attempt to use the RO FS?

@BrutalBirdie said in Error installing community nodes on n8n:
I am not sure but it looks like it.
I just tried adding this to the ..EXTERNAL but i seems did not have the desired effect.
@girish maybe you can chime in and give some insight.
I guess this module as to be added via us devs?As I understand it, there is no possibility to add community nodes in Cloudron-n8n.
Unfortunately, I am also not skilled enough to perform such actions directly at the server level. -
Has anyone ever installed a n8n-community-node on their cloudron-n8n and can tell me how?
I am trying to install the following node 'n8n-nodes-ninox' via settings and failing miserably.

If the modules are deployed dynamically
Let's make n8n great again
I believe it's a relatively new function in n8n; it's under setup
while on the cloudron log side it's look like:

Having the same issue, I think cloudron package need to be modified to allow community nodes to be installed.
n8n-nodes-rss-feed-trigger

The old way of packaging custom npm modules could be ditched in favor of the ability to install community nodes https://www.npmjs.com/search?ranking=popularity&q=keywords%3An8n-community-node-package
is there any plan to do so ?
-
@benborges how does this work from a deployment perspective. Let's say you deploy 5 custom node modules. What happens after an update? How is the installation of these modules tracked ?
I checked their SaaS offering and they don't allow installing community modules.
Any suggestions welcome.
-
I just tried the upstream offering and found that n8n cloud does not support community modules, not even in the latest version. I am questioning now if it makes even sense for us to bend around making that possible, which will surely result in breakage if community modules are not updated and tested against new n8n versions. If upstream can't even support this, while they have per-customer instances (probably also some kind of containerization) I don't think we can support that.

I know next to nothing about this, but perhaps it's just like hosted WordPress.com (where basically no plugin are allowed, unless you upgrade and then a few become available), and self-hosting WordPress where you can install as many plugins you like.

@benborges yeah, I was only checking if you know how this works deployment wise. Atleast, upstream I cannot find information about this.

@UweG said in Error installing community nodes on n8n:
Is it generally not possible to install community nodes on Cloudron-n8n?
It is possible, I am using io.n8n.cloudronapp@2.14.0 (n8n v0.201.0):
- open the app terminal
- go to custom extensions folder
cd /app/data/custom-extensions/
- install your desired community packages, e.g.
npm i n8n-nodes-directus
- start editing the file
/app/data/env
with the File Manager and add these line:
export N8N_CUSTOM_EXTENSIONS=/app/data/custom-extensions/
- Last but not least: restart the app and find the node in the Add Node panel
-
@dev-cb Ohhh this is exciting, wondering what happens if N8N gets an upgrade that breaks a community node..what would be the upgrade path? wait for community node upgrade, then upgrade existing installed custom packages and restart N8N ?
-
OK, I found some interesting notes at https://docs.n8n.io/integrations/community-nodes/installation/ . Investigating if that works for us.
edit: https://docs.n8n.io/integrations/community-nodes/troubleshooting/ is a better link
