[JeroenMBooij]

in production build I get the error saying Cannot find module electron-log/main when I start the application

I have an electron app that is wrapping a Angular app and I use electron-build to build the app

That's a bundling issue. I need a sample project that reproduces the problem so I can determine what's wrong.

[kogratte]

I got something very,very, very similar on a nuxt+electron project.Obviously,path are slightly differents, but the error is the exact same.

[kogratte]

Ok, I got something.

You CANNOT use electron-log from the background process. Anyway, stderr and stdout are redirected if using process.fork or spawn,so,logs ends up in the logfile managed by electron-log.

Remember that the background process should theoretically be runnable as a standalone node program.
