Hi guys, Could anyone tell me how to download the modbus in node red. I try to download using the manage palette but its shows error and I also try download using cmd. Its also failed. So could anyone tell me how to download it? I'm using a node red in windows. Thank you in advance.

Welcome to the forum.

2 things...

- you really should be running stable Node Js (not v17)
  - I would recommend V16 LTS or 14 LTS

- The errors show it cannot find Python.

When you install NodeJS it asks if you want to install "Build Tools" - inside Build Tools is Python and all the compiler stuff needed for things that need compiling (like the Serial Port code inside Modbus nodes)
