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 winfunction 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 Qif (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=0.1.0 --electron-version=1.6.15 --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。
