Cannot find module '***' [Windows]

[cmzz]

• Version: 19.16.0

• Target: windows 7 x64

Im building an app on windows. When build success and run app , then got error "Cannot find module "ultron".

If add "ultron" to dependencies, got an other error : "Cannot find module "safe-buffer".

I know issuse 217 but cannot work for me . module.paths is undifined ?

Anyone have ideas..

You see, if build on mac, more modules did put in than build on windows in win-unpacked\resources\app\node_modules folder

try rebuild,electron-rebuild

[develar]

@hengkx Not required, electron-builder automatically rebuilds.

[develar]

Please set env DEBUG=electron-builder:* and attach log of the terminal output.

@develar Thanks for help.

[cmzz]

@develar Its work fine with version 19.10.0

[develar]

@cmzz Could you please provide project to reproduce?

[cmzz]

@develar Sure

github repository

[cmzz]

@develar Above version 19.13.0, Cannot pack all npm module.

19.13.0 => 2100+ object in build\win-unpacked\resources\app\node_modules
19.14.0 => 200 object in build\win-unpacked\resources\app\node_modules

[develar]

Do you use npm or yarn? Please remove package-lock.json, yarn.lock and node_modules And install using yarn (not npm) again.

[develar]

As far I see (in my case solution "remove package-lock.json" helps), DO NOT USE F**** NPM. Sorry for capslock, but please do not ever use npm and never store package-lock.json (if you use npm by error, remove created package-lock.json after it and use only yarn).

[develar]

Tip: node-notifier not required anymore — latest electron can show notifications from main process.

[cmzz]

@develar Aha thanks... Its work for me now. FUCK NPM

Hi,
i solved it by migrating from npm to yarn.. that worked!!

[orzechdev]

I had the same issue with pnpm. After migrating to yarn the issue is solved. But what was the reason and why it doesn't work with pnpm?

[dieharders]

I spent all day trying to get this to work. Switching from PNPM to YARN worked for me. No idea why pnpm doesn't work but npm is referenced in the docs as if you have a choice but you dont.

Yarn should really be documented as the ONLY package manager that works with electron-builder (again, NO idea why? someone enlighten me?)
