电子：找不到模块“电子预建”

Question

I have an Electron app that uses Nightmare.js when one of the buttons is clicked. It works fine before being packaged, but after I compile it to an .exe file with electron-packager, it will work as intended, until I click the button that makes use of Nightmare.js. I get this error:

Uncaught Error: Cannot find module 'electron-prebuilt'

Answer 1

Make sure electron-prebuilt had been added into development dependency in your package.json . You can install module by npm install --save-dev electron-prebuilt

The correct way to require the app module in Electron is:

const {app} = require('electron')

Hope it help.
