G-Mercier commented 2 years ago

Hi,

I tried to install the contribution on my pc (windows 10) to test RFXcom possibilities with node red. 1/Using powerShell interface I've installed the package using "npm install node-red-contrib-rfxcom". 2/ Reboot NodeRed 3/ Try to find the nodes in the palette, but don't show up. 4/ in Palette Manager, the package is said installed but ERR_DLOPEN_FAILED appears

This is a new error to me! Apparently it is something to do with loading a C++ native module directly, used in the internals of require. If the load fails the ERR_DLOPEN_FAILED error is raised. I have no idea why it is happening to you.

It might be because of a node.js version mismatch between the version used to compile serialport (which the rfx-port node uses) and the node version you are running, but that is normally detected when npm install runs, and if so, the C++ source is downloaded and recompiled.

Which versions of node.js and node-RED are you using?

Hello Max, First thanks for your quick response. It might also just be me and my poor skills in node red. Any way currently my computer runs:

3 Jan 14:46:06 - [info] Node-RED version: v2.1.4 3 Jan 14:46:06 - [info] Node.js version: v16.13.1 3 Jan 14:46:06 - [info] Windows_NT 10.0.18363 x64 LE

Hello Again,

I've tried to uninstall node.js + delete .node-red folder and re-install everything. Apparently it worked ! Now I can access the rfx nodes. Regards

G

Glad to hear it is working again. Presumably a file got corrupted, or installed in the wrong place, or something, in the original installation
