modules (dependencies) don't work: Error: Cannot find module

[ryancwalsh]

My first fiddle attempt.

I wanted to create a fiddle to report a bug with robotjs, but I get this error even though I specified the dependency:

App threw an error during load
Error: Cannot find module '@jitsi/robotjs'
Require stack:
- /tmp/electron-fiddle-90379-VDHq4ptMJ80k/main.js
- /home/myname/.config/Electron Fiddle/electron-bin/current/resources/default_app.asar/main.js

https://gist.github.com/ryancwalsh/0867273c6c0199b55d2a314525f61f63

What am I doing wrong?

I'm on Ubuntu.

Thanks!!

P.S. Is there a way to use TypeScript (and import instead of require)? It's kind of a hassle to translate my code into old JavaScript.

@ryancwalsh see electron/electron#37535 for esm - new in latest major. Unfortunately Fiddle does not support Typescript.

This looks unfortunately like temporary npm issue or something, because i had no issues:

I also added:

const robot = require("@jitsi/robotjs");

console.log(robot.getScreenSize())

to main.js and saw { width: 1728, height: 1117 } printed as expected to console.

@codebytere Thanks for your response!

It's still not working for me. I'm a first-time Fiddle user, so it's just an assumption, but I'd think that what you probably did was open Fiddle, paste my Gist URL into the field at the top right, press Load Fiddle, and press Run.

I tried again just now (on Ubuntu), and this is the error I get:

Thanks.

Any new ideas, anyone? Thanks!

This looks like your issue. You're likely missing this package on Ubuntu - once you install it the issue should likely resolve.

[ryancwalsh]

Thanks for this idea, @codebytere !

Unfortunately it seems I already have make installed, so I don't know why I'm getting that error.

sudo apt-get -y install make

make is already the newest version (4.3-4.1build1).

Update: My Ubuntu laptop just froze, so after a forced restart, I tried again, and now I'm getting this error even though I do have Yarn installed according to:

yarn -v
1.22.19
