Installing udmx node


if i wat to install the npm i node-red-contrib-udmx node i get a error.
does sombody know why?
i am using a rbp 3b.


Because something has gone wrong? :upside_down_face:

If you post the actual error someone might be able to suggest what to do. Without the error, it would only be guesswork. But also please include the versions of Node-RED, node.js (listed on start-up message of Node-RED) and which platform you are running on

i am using node red version: v0.19.3


You have an ancient version of npm, you are on 1.4.21, the latest is 6.x. Since it seems you are on a pi then, assuming you are running Raspbian, I suggest updating everything using the recommended pi install/upgrade script in the docs


After you have upgraded.... then the main error is that there is library missing so it won't compile...

../libusb/libusb/os/linux_udev.c:40:21: fatal error: libudev.h: No such file or directory
#include <libudev.h>

so you need to do

sudo apt-get update && sudo apt-get install libudev-dev

then retry the install


sow i did the upgrade and did the sudo and now i am able do instal it.
thanks to you all

sow i orderd a usb dmx dongle to work with the udmx node.
now i have the problem that the udmx node does not reccunice the usb dongle.
i think i have to instal the drives for the usb dongel.
can you tell me how to do that?


iā€™d start by googling the name of the usb dongle you have bought and linux


Sow i googled it but i can not find a linux driver.
sow probelley i orderded the wrong usb dmx dongle.
can somebody tell me witch dongle will work with the udxm node and a raspberry pi?
