The upgraded node requires Node.js v14, 16 or 18 as a minimum.
I have already carried out the upgrade of Node-Red on a 'vanilla' Raspberry Pi running Raspian. To do this I needed to install NVM to successfully get Node.js v16 installed. For reasons unknown to me, a manual upgrade of Node.js to v16 kept reverting to v12 upon reboot. The install of NVM fixed this anomaly.
Going forward, is there a safe way to upgrade the Loxberry Node.js instance? What commands should be run?
