Electron

Electron踩坑

参照官方文档，用npm init初始化完一个electron项目后，开始安装electron，结果由于某种原因electron的一个zip包一直下载不了，画面卡在如下截图中，：

网上很多解决办法基本都是千篇一律，要么手动下载zip文件，然后移动到指定位置，要么是npm配置ELECTRON_MIRROR="https://cdn.npm.taobao.org/dist/electron/"，都不起作用，知道是网络原因，但替换了淘宝的npm源依然解决不了，最后尝试使用cnpm：

1
npm install cnpm -g  --registry=https://registry.npm.taobao.org

死马当活马医，最后居然安装成功了：

最后，跑个demo试试：

// main.js
const { app, BrowserWindow } = require('electron')

function createWindow () {
  // Create the browser window.
  const win = new BrowserWindow({
    width: 800,
    height: 600,

  // and load the index.html of the app.

app.whenReady().then(createWindow)

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', () => {
  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 (BrowserWindow.getAllWindows().length === 0) {
    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.
