electron 开发时最麻烦就是electron版本和node版本的选择和正确安装
electron 用npm安装时太慢容易报错，建议用cnpm i 进行安装
注意最新版渲染进程使用node
nodeIntegration: true, // 渲染进程可用node
contextIsolation: false, // 这个值影响nodeIntegration是否生效electron 的主进程的创建
function createWindow () {// Create the browser window.const mainWindow = new BrowserWindow({width: 800,height: 600,webPreferences: {nodeIntegration: true, // 渲染进程可用nodecontextIsolation: false, // 这个值影响nodeIntegration是否生效preload: path.join(__dirname, 'preload.js')}})// and load the index.html of the app.mainWindow.loadFile(path.join(__dirname, 'index.html'))// Open the DevTools.mainWindow.webContents.openDevTools()// 渲染进程使用remote remote.enable(mainWindow.webContents)//3require("./ipcMain/menu")require("./ipcMain/rightMenu")// 主进程发送消息mainWindow.webContents.send("mainMag","发财发财")
}app.on('ready', createWindow);
