Reproducible Demo

https://github.com/rambabusaravanan/error-create-react-app checkout the latest commit and npm install and perform npm run build

I'm building a cross-platform desktop app using electron and react and I'm using npm package 'node-thermal-printer' for usb thermal printer. The printer code works fine in the places where react-scripts build doesn't involve like

• static .js (public folder) and linked to index.html (renderer process)
• electron's main process (main.js)

But the code fails, when I add the same code in src/index.js where react-scripts build failed with error code ELIFECYCLE, errno 1
