@Lawrence
I checked the following site : https://libraries.io/npm/node-red-contrib-modbus/0.4.8
I don’t know if I can trust it, but from the version 0.4.8 the nodejs requirement was 0.13.4.
Comments above show that we have limitations, because our nodejs version of Conduit gateway is 0.11.1 and can’t be updated :
However, it is not possible to upgrade nodejs beyond 0.10.x due to the Conduit being restricted to the armV5tej instruction set.
In your case, do you remember the version of nodejs and npm that you have used before ? It is nice of you to ask your friends about their versions.

I tried to install pymodbus two hours ago. I had some compilation errors but the package pymodbus seems to run.
With your advice i’m going to reinstall pymodbus
