我使用HTML，CSS和JS创建了一个计算机应用程序，但当我尝试使用electron-packager将该应用程序转换为exe文件时，它显示错误

无法从'C：// myapp / helloworld /'找到模块'electron-prebuilt'

我正在使用Windows。

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.

Answer 1

npm install --save electron-packager

或者，如果您使用的是两个package.json结构，则可以尝试

npm install --save electron-packager

在/ app和更高目录中。

此外，运行npm run pack命令时会发生此错误吗？

Answer 2

从npm文档中：

从1.3.1版开始，此软件包以两个名称发布到npm：电子和电子预建。您目前可以使用任何一个名称，但是推荐使用电子，因为不赞成使用电子预建名称，并且只会发布到2016年底。

下载并安装适用于您操作系统的最新版本的Electron并将其作为devDependency添加到项目的package.json中：

npm install electron --save-dev

这是使用Electron的首选方式，因为它不需要用户   全局安装Electron。

您还可以使用-g标志（全局）将其符号链接到您的PATH中：

npm install -g electron
