【问题描述】：

我的应用在构建时不显示窗口，但在我运行 npm run serve 时工作正常

任务管理器中仍然有一个进程在运行，如果我使用安装程序也会发生同样的事情。我没有收到来自 electron-builder 的任何错误警告。

background.js：

import  app, protocol, dialog, BrowserWindow, ipcMain, shell  from 'electron'
import  createProtocol  from 'vue-cli-plugin-electron-builder/lib'
import installExtension,  VUEJS_DEVTOOLS  from 'electron-devtools-installer'
import path from 'path'
import fs from 'fs'
import childProcess from 'child_process'
import ncp from 'ncp'

const isDevelopment = process.env.NODE_ENV !== 'production'

// 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

// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([
   scheme: 'app', privileges:  secure: true, standard: true  
])

function createWindow () 
  // Create the browser window.
  win = new BrowserWindow(
    width: 1200,
    height: 600,
    resizable: false,
    maximizable: false,
    frame: false,
    webPreferences: 
      // Use pluginOptions.nodeIntegration, leave this alone
      // See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
      nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,
      preload: path.join(__dirname, 'preload.js')
    
  )

  if (process.env.WEBPACK_DEV_SERVER_URL) 
    // Load the url of the dev server if in development mode
    win.loadURL(process.env.WEBPACK_DEV_SERVER_URL)
    if (!process.env.IS_TEST) win.webContents.openDevTools()
   else 
    createProtocol('app')
    // Load the index.html when not in development
    win.loadURL(path.join(__dirname,'index.html'))
  

  win.on('closed', () => 
    win = null
  )


// 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()
  
)

我尝试了修复 here 和 here 无济于事。

我正在使用电子-vue。如果您需要更多上下文，可以找到完整代码here

【参考方案1】：

问题最终出现在 app.on('ready') 函数中。在创建窗口后需要编写任何额外的代码，否则会出现问题。
