记一次使用Node.js electron打包网站的记录

具体步骤请参考：http://blog.csdn.net/a727911438/article/details/70834467

打包时出现了不少问题，逐一记录下来以供其他人参考。

package.json文件内容

{
  "name": "appname",
  "version": "0.1.0",
  "main": "./main.js",
  "scripts": {
    "start": "electron ."
  }
}

main.js文件内容

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: , height: })

  // 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.

安装好打包神器后，在执行 electron-packager时出现“Unable to determine Electron version. Please specify an Electron version”错误：

要解决这一问题，只需在命令中指定Electron version，具体命令如下：

electron-packager . sound_machine --win --out a --arch=
x64 --version=0.1. --electron-version=1.6. --overwrite --ignore=node_modules

由于本地网络采用的是服务器代理上网模式，因此还需为npm指定代理地址，否则会出现“tunneling socket could not be established, statusCode=502”的错误。

设置npm代理的命令如下：

npm config set proxy=http://10.**.**.**:8080

再次执行 electron-packager打包命令，这次没有错误了，提示开始下载文件。下载完成后开始打包，提示打包成功：

至此，打包完成。
