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,
webPreferences: {
nodeIntegration: true
}
})

// and load the index.html of the app.
win.loadFile('index.html')

// Open the DevTools.
win.webContents.openDevTools()
}

// 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.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.
