KerlinkGateway - Installation of node red

Hardware
1

Hello,
I would like to install node-red on Kerlink iFemtoCell-evolution 868.
I managed to install node.js and npm manually but when I try to install node-red I receive errors like in code below.
Can anyone help me to solve this issue and tell me what is wrong?
Some informations about Linux installed on the gateway

Linux klk-fevo-03009F 4.14.9-klk #1 SMP Tue Sep 24 13:11:43 CEST 2019 armv7l GNU/Linux

Have you tried running node-red?

I think it installed but some components cannot be compiled (you likely wont be able to use serial port) - this is likely due to the environment (might need to install build-essential)

Ok, we need a broader point of view.
I have tried to run node-red and it works but in fact it was not the main issue. The main idea is to translate LoraWan telegrams to Modbus TCP request with usage of node-red. To do it i need to install ModbusTCP library. But when I do it I receive errors which I have placed below. This is not common hardware like raspberry pi and probably that's the main problem but still, maybe someone can help with it?

as Steve hinted you probably need the build-essential tools package installed
and you may want to try installing manually but adding the --unsafe-perm parameter to the command - so npm install --unsafe-perm --no-audit --no-update-notifier --no-fund --save --save-prefix=~ --production node-red-contrib-modbus@5.13.3 from within your .node-red directory.

#cichy28 are you running Wanesy™ SPN2 for Small Private Network on the Kerlink?
Wonder if your better off running Node-RED on separate device like a RPI or Industrial RPI.

@iiLaw
Yes, i think it is Wanesy™ SPN2 for Small Private Network, but normally node-red is part of it ( at least version 0.18).
In the beginning, I thought that it will be a simple task to do add a proper library to the node-red but as you see I have some problems. In the end, I think that adding RPI as a gateway may be the simplest and the fastest solution.

@cichy28 I've had similar issues with Multitech Conduit AEP it has LNS & Node-RED. But is suck on very old version of nodejs so some custom nodes don't work Modbus :frowning: being one. The MT AEP runs Yocto (as does the Kerlink) but MT doesn't ship with C/C++ compiler which has ruled out some custom nodes.

What has worked well is a MQTT broker and NR on a separate device. If timing is key we use https://revolution.kunbus.de/shop/en/hardware as they have integral RTC they have NR pre installed.

BTW does Wansey SPN2 app server support MQTT or REST for up/downlink integration?
