Trouble Installing NCD Node Red Nodes

I’m trying to get Node Red setup with these products so I can periodically write the data from the thermocouple sensor to a CSV file. I’ve never used Node Red before, and I’m trying to follow your tutorial at (https://ncd.io/setting-up-node-red-wireless-sensor-network/). I’ve got Node Red installed and have successful created some of their demo flows. I’m trying to install your custom NCD nodes and it doesn’t appear to be working because after I run the installation command (https://ncd.io/setting-up-node-red-wireless-sensor-network/), then relaunch Node Red, I don’t see any nodes when filtering on “ncd”. See below for the output from Windows 10 PowerShell when attempting to install your nodes…

PS C:\Users\295159> npm i ncd-red-wireless node-red-dashboard

Hi,

These errors seem to be related to your installation of Python. I would recommend doing some research on installing Python and Python3 on your Windows computer.

Are you attempting to install the NCD Node-Red libraries through the command prompt or through the pallet manager inside of Node-Red?

I ran into this a few days ago, the issue actually seems to be related to the serialport library. I solved it by deleting the node_modules folder, rolling back to node 12, and then running npm i from the node-red directory to reinstall and rebuild all binaries and libraries.

Also, if you plan to use node red and haven’t already, look into installing nvm (node version manager). It is extremely helpful for situations like this when a dependency library has outstanding issues for the latest versions of node.

Thank you Trey. I uninstalled node 14.x and then installed node 12.20 and I was able to install ncd-red-wireless.
