but the file indeed exist.

Steps to reproduce

1. install electron forge

npm install --save-dev @electron-forge/cli
npx electron-forge import

2. run make cammand and package.json's main including 'out' folder

npm run make

{
  "main": "./out/main/index.js",
}

Additional information

If I rename out folder to dist folder, the issue will be fixed. I deduced that it was a folder naming conflict. I would like to improve the error message.
