Electron-packager missing module 'electron-prebuilt'

Question

I made a computer app using HTML, CSS and JS but when I try to convert that app to exe file using electron-packager it shows me error

Cannot find module 'electron-prebuilt' from 'C://myapp/helloworld/'

I am using windows.

This is the code

Main.js

const {app, BrowserWindow} = require("electron");
const path = require('path')
const url = require('url')

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win

function createWindow () {
  // Create the browser window.
  win = new BrowserWindow({width: 800, height: 600})

  // and load the index.html of the app.
  win.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))

  // Open the DevTools.
  win.webContents.openDevTools()

  // Emitted when the window is closed.
  win.on('closed', () => {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    win = null
  })
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (win === null) {
    createWindow()
  }
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

I'm not familiar with electron, but would you need to do a `require('electron-prebuilt')`? In your Main.js right below `const {app, BrowserWindow} = require("electron");` — MannfromReno, Jan 25 '17 at 20:40

npm install --save electron-packager

Or if you're using a two package.json structure, you could try

npm install --save electron-packager

in both /app and higher directory.

Also, does this error occur when you run the npm run pack command?

Did you run `npm install --save electron-packager`? – Codin Moldovanu Jan 25 '17 at 21:36

From the npm documentation:

As of version 1.3.1, this package is published to npm under two names: electron and electron-prebuilt. You can currently use either name, but electron is recommended, as the electron-prebuilt name is deprecated, and will only be published until the end of 2016.

Download and install the latest build of Electron for your OS and add it to your project's package.json as a devDependency:

npm install electron --save-dev

This is the preferred way to use Electron, as it doesn't require users to install Electron globally.

You can also use the -g flag (global) to symlink it into your PATH:

npm install -g electron
