Electron 带 Strapi，找不到模块 package.json

Question

I built an application using strapi , i am trying to package it inside electron using electron-builder.

The packaging is done well, but when i start the app, it shows this message

PS E:\Development\DentalSystem\dentalBE_test\dist\win-unpacked>

What seems to be the problem is that my application is looking to package.json file inside the root folder (directly relative to the exe file), while it exist inside the (app) folder with all other resources of the system.

this is my package.json file

{
  "name": "DentalSys",
  "main": "./index.js",
  "version": "0.2.0",
  "description": "Dental Clinic Management System",
  "productName": "DentalSys",
  "build": {
    "appId": "com.kldoon.dentalSys",
    "asar": false    
  },
  "scripts": {
    "develop": "strapi develop",
    "strapi-start": "strapi start",
    "strapi-prod": "cross-env NODE_ENV=production npm start",
    "strapi-build": "strapi build",
    .....
  },
  "devDependencies": {
    "concurrently": "^5.1.0",
    "electron": "^9.1.2",
    "electron-builder": "^22.4.1",
    ......
  },
  "dependencies": {
    "knex": "0.20.13",
    "moment": "^2.27.0",
    "sqlite3": "^4.1.1",
    "strapi": "3.0.0-beta.17.5",
    .......
}

And this is my electron (index.js) file

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

const strapi = require('strapi');
//const { exec } = require("child_process");

function createWindow() {

    // Create the browser window.
    const win = new BrowserWindow({
        maximizable: true,
        title: "Dental System",
        webPreferences: {
            nodeIntegration: true
        }
    })
    win.maximize();

    strapi().start().then(() => {
        win.loadURL('http://localhost:49862/');
    }).catch((e) => {
        console.log(e);
    });

    win.on('closed', () => {
        app.quit();
    })
}

app.whenReady().then(createWindow)

app.on('window-all-closed', () => {
    if (process.platform !== 'darwin') {
        app.quit()
    }
})

app.on('activate', () => {
    if (BrowserWindow.getAllWindows().length === 0) {
        createWindow()
    }
})

I tried multiple solutions but none work, i hope someone can help with it.

Thanks in advance.

It turned out to be easy fix, with dir option of strapi constructor

strapi({
dir: __dirname + '/'     ///<==== add this 
}).start().then(() => {
  win.loadURL('http://localhost:1337/');
}).catch((e) => {
  dialog.showMessageBox(win, { message: JSON.stringify(e) });
  console.log(e);
});
