Steps to reproduce

The issue happens when I have a dependency to a local library using a relative path. Sample package.json

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "build": "./node_modules/.bin/tsc",
    "start": "electron-forge start",
    "package": "electron-forge package",
    "make": "electron-forge make"
  },

// other options.....

  "dependencies": {
    "<my-local-library>": "file:../../../" (relative path to the library),
    },

Simply run npm run make could reproduce the issue.

Additional information

I did not see the issue if I use a version number instead of the relative path for the dependency. However, I would like to to build the application with my local distribution instead of the public version.

Besides, it seems that the issue does not occur when running electron-packager directly:

> npx electron-packager . --overwrite

I was able to package the sample without errors running the commands above.

Electron-packager had a similar issue and it has been fixed in 8.5.2. It could be related or similar: https://github.com/electron/electron-packager/issues/396
