Electron-packager: cannot find module

I trying to package my app using electron-Packager and this command:

electron-packager . FooBar --platform=darwin --arch=x64 --version=0.36.9

(I'm using MacOsx) the app is created but when I run it I get a pop-up showing this:

Uncaught Exception:

Error: Cannot find module '/Users/myUser/myApp/FooBar-darwin-x64/FooBar.app/Contents/Resources/app/app:/host/menu.html'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:289:25)
    at Object.<anonymous> (/Users/myUser/myApp/FooBar-darwin-x64/FooBar.app/Contents/Resources/atom.asar/browser/lib/init.js:158:8)
    at Module._compile (module.js:425:26)
    at Object.Module._extensions..js (module.js:432:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:313:12)
    at Function.Module.runMain (module.js:457:10)
    at startup (node.js:151:18)
    at node.js:1007:3

in this folder : "/Users/myUser/myApp/FooBar-darwin-x64/FooBar.app/Contents/Resources/app" there is the entry pointing html file "menu.html", but it seems electron cannot find it...

this is my app.js:

var app = require('app');  // Module to control application life.
var BrowserWindow = require('browser-window');  // Module to create native browser window.

var mainWindow = null;


// This method will be called when Electron has done everything
// initialization and ready for creating browser windows.
app.on('ready', function() {

  // Create the browser window.
  mainWindow = new BrowserWindow({width: 1024, height: 768});

  // and load the index.html of the app.
  mainWindow.loadUrl('file://' + __dirname + '/menu.html');

  mainWindow.openDevTools({detach: true});

  // Emitted when the window is closed.
  mainWindow.on('closed', function() {
    mainWindow = null;
  });

});

Do you have any ideas on what could be the problem?

Thank you.

What worked for me was whatever dependency you are trying to install, instead of having --save-dev just use --save

For me, I had to rebuild the electron app. Working with Ionic, first delete the /electron folder, then run:

npx cap add electron

what worked for me was modifying the reference to the main application file ie : main.js for newer electron versions or app.js for old versions of electron in package.json as follows :

"main": "app.js"

So i had this same problem. Mine got solved when i cd in to my project folder and did

npm i -D electron@latest

Sometimes adding in package.json and npm install would not have installed it properly. Please lemme know if it worked for you.

For me the problem was that the module dependencies were listed in "devDependencies" in package.json

Moving them to "dependencies" and running npm install again solved the problem.
