Welcome to forums @Por1995

Have you recently updated your node version?

This error usually occurs when a native Node binary was compiled using a node version, that it is no longer running under.

within the .node-red dir run npm rebuild

[Por1995]

yes I update node version I'll try npm rebuild. thank

[Por1995]

now I run npm rebulid but is ERR!

how can I fix

[marcus-j-davies]

Try running cmd with elevated privileges - i.e run as administrator
you will then need to cd to the .node-red dir

as the cmd window will initiually be running under the systems32 folder.
but npm rebuild needs to run under your .node-red dir

I don't actually use windows (for anything) - so maybe someone who is better qualified in windows can clarify

thank a lot now I can use modbus serial
