Hi all,

I'm trieing to install node-red-contrib-serialport-rs485 om my raspberry pi (node red V 1.0.0) but i get following error:

> npm ERR! code E404  
> npm ERR! 404 Not Found - GET [https://registry.npmjs.org/node-red-node-serialport-rs485](https://registry.npmjs.org/node-red-node-serialport-rs485) - Not found  
> npm ERR! 404  
> npm ERR! 404 'node-red-node-serialport-rs485@latest' is not in the npm registry.  
> npm ERR! 404 You should bug the author to publish it (or use the name yourself!)

> 
> npm ERR! A complete log of this run can be found in:  
> npm ERR! /root/.npm/\_logs/2020-11-20T09\_45\_55\_935Z-debug.log

Possibly because in the install command you typed node-red-node-serialport-rs485 instead of node-red-contrib-serialport-rs485

Searching the forum for node-red-contrib-serialport-rs485 finds this thread which concluded that the node is unsupported and not installable I am sorry to say. [Rs485 serialport plug in](https://discourse.nodered.org/t/rs485-serialport-plug-in/14388/)
