Can't use the `serialport` module (building for electron)
I’m trying to use the
serialportmodule from npm, but it doesn’t work.
The error can be reproduced by creating a blank quasar project,
npm install serialport, and adding this to
import * as serialport from 'serialport' console.log('serialport:', serialport)
I get the following error:

@r03ert0 I found a base project using this npm package. You can see the implementation here:
thank you @patryckx !
i can’t see what it’s being done differently in that project… for me, just the fact of importing
serialporttriggers the error!

Yeah, I used serialport a LONG time ago - on Linux - and had huge problems figuring out which usb to use. I don’t remember exactly what the solution was, but my hunch is that it has to do with your OS

argh… I’m on a Mac.
I did manage to use serialport in a node-only command, but i’m a bit lost among all the layers that quasar adds.
I found someone posting a similar issue, which was related to webpack, but i don’t know what to do with that information: https://github.com/serialport/node-serialport/issues/1789

Generally when I am faced with this kind issue I start at the bottom and work my way up - this means specifically making sure that node-serialport is REALLY working.
Nevertheless, from that issue there one takeaways that MIGHT help you:
- use node-serialport v6.2.2
but I found this in serialport’s installation guide (https://serialport.io/docs/guide-installation):
Electron Electron is a framework for creating cross-platform desktop applications. It comes with its own version of the Node.js runtime. If you require serialport as a dependency for an Electron project, you must compile it for the version of Electron your project's using. When you first install serialport it will compile against the version of Node.js on your machine, not against the Node.js runtime bundled with Electron. To recompile serialport (or any native Node.js module) for Electron, you can use electron-rebuild; more info at Electron's README. npm install --save-dev electron-rebuild Add electron-rebuild to your project's package.json's install hook Run npm install For an example project, check out electron-serialport.
but that didn’t help either… How can I check which version of Node is electron using?
