node module version conflict when installing modules for electron

Question

I\'m trying to make an Electron application (https://electron.atom.io/) that reads data from my serial port. I\'m new to web technologies in general, I know some javascript,

Answer 1

electron-rebuild on postinstall.

Depending on what you're doing, you can use electron-rebuild to rebuild serialport to the version of electron you have installed.

To do so:

npm install --save-dev electron-rebuild

$(npm bin)/electron-rebuild                 # Mac and Linux.

.\node_modules\.bin\electron-rebuild.cmd    # Windows.

Because I kept forgetting to do this after doing an npm install (and to help others that downloaded the project), I added the following two scripts to package.json:

"scripts": {
  "start": "electron .",

  "postinstall": "electron-rebuild",    
  "electron-rebuild": "electron-rebuild"
},

The postinstall will automatically run after doing a npm install so after the typical install finishes you'll see a console log message with electron-rebuild and it will automatically rebuild serialport, and any other native library you have, to the electron version. This means that you shouldn't even have to think about running electron-rebuild going forward.
