Can not find module 'debug - electron

Question

I've been having this issue for a while and I've even opened an issue on electron-builder github page but haven't received any response.
I'm running electron builder version 20.38.4 and trying to package the app for Win 64 environment. Everything works fine when I do "yarn dev" and "yarn compile". Even "yarn dist" works without any issue.
However, when I click on the generated .exe file, I get this error message.
Any ideas?
Here's the link to the issue I've opened with some detailed screenshots and log outputs

Answer 1

Sorry to revive an old question, but what is happening is the electron-online package does not properly define its dependencies in its own package.json. So it is missing the debug package, which you have "solved" by placing another package that requires debug in your project dependencies. In reality though, the (long abandoned) package electron-online should update its dependencies and add debug, among others.
As a slightly cleaner workaround, you could add debug to your project dependencies instead of electron-webpack or webpack.

I had the same problem a few hours ago, resolved by not excluding (ignoring) the src folder from package config. Could you paste you package.json file here ?

Answer 3

Ok. Looks like I've solved my own problem. Not sure why exactly but it worked. What I had to do was move 2 dependencies listed below from devDependencies to dependencies section in my package.json
"electron-webpack": "^2.6.1",
"webpack": "^4.26.0"
If someone can shed some light on that, it'd be helpful. I figured I'd post it here in case someone else runs into this issue.
