I am trying to install Node-red-contrib-modbus from the web interface, but it just shows the progress bar and then disapears. if i try and install from a SSH window i get an error
pi@emonpi(rw):node-red$ npm install node-red-contrib-modbussudo

By the error message I would guess you’re on an older version of node.js and maybe an old version of npm. And node-red-contrib-modbus wants newer versions.
I am on these versions:
Node-RED version: v0.17.5
Node.js version: v6.11.4
npm version: v3.10.10
