Module version mismatch. Expected 49, got 48 on Node 6.3.0

Hello,

I recently upgraded to node 6.3.0 and npm 3.10.5, I use mdns 2.3.3, everything installs fine with npm install (after i have rm -rf node_modules) but when I launch the app mdns fails with a message:

Error: Module version mismatch. Expected 49, got 48.

... and the stack goes on ...

This is an Electron application running on electron 1.3.1

Any advice is welcome

The add-on was build using one version of node and plugged into a different version, the one that ships with electron.

Make sure you build the add-on the electron way (not an expert here).

thank you @agnat! running ./node_modules/.bin/electron-rebuild did the trick
