Hi @I2rys,

I got the same or similar problem. After research I found this change https://github.com/electron/electron-packager/pull/819 since then you have to take care of the pruned node_modules by yourself.

See also the readme "usage"

...Be careful not to include node_modules you don't want into your final app. If you put them in the devDependencies section of package.json, by default none of the modules related to those dependencies will be copied in the app bundles. (This behavior can be turned off with the prune: false API option or --no-prune CLI flag.) In addition, folders like .git and node_modules/.bin will be ignored by default. You can use --ignore to ignore files and folders via a regular expression (not a glob pattern). Examples include --ignore=.gitignore or --ignore=".git(ignore|modules)"...

an prune:false worked for me
