我用的打包工具: electron-builder

1、在package.json 文件的同级下创建2个js文件 

     electron-builder-test.config.js   electron-builder.config.js

electron-builder-test.config.js

const basejson = require('./electron-builder.config.js');
module.exports = {extraMetadata: {  //  这个是重点，这个字段会在build的时候将NODE_ENV这个变量插入package.json文件中，所以我们才能    //  在别的文件中读取package.json得到NODE_ENV这个字段值，用来判断当前环境是生产还是测试NODE_ENV: process.env.NODE_ENV,},...basejson
};

electron-builder.config.js  （主要就是一些build的基础配置）

module.exports = {productName: 'yourProductName',nsis: {include: './lib/deleteTempFiles.nsh',oneClick: false,allowToChangeInstallationDirectory: true,installerIcon: './app/icons/icon.ico',uninstallerIcon: './app/icons/icon.ico',installerHeaderIcon: './app/icons/icon.ico',installerSidebar: './app/icons/mark.bmp',uninstallerSidebar: './app/icons/mark.bmp',perMachine: true},files: ['src', 'service', 'app', 'const', 'lib'],appId: '',mac: {publish: [{provider: 'generic',url: ''}],gatekeeperAssess: false,hardenedRuntime: true,entitlements: './signing/entitlements.mac.plist',entitlementsInherit: './signing/entitlements.mac.plist',extendInfo: {NSMicrophoneUsageDescription: 'Please give us access to your microphone',NSCameraUsageDescription: 'Allow your conversational partners to see you in a Grape Call. You can turn off your video anytime during a call.'},icon: './app/icons/icon.ico',extraFiles: [{from: './app/icons/',to: './Resources',filter: ['**/*']}]},win: {publish: [{provider: 'generic',url: ''}],icon: './app/icons/icon.ico',target: [{target: 'nsis',arch: ['x64']}],extraFiles: [{from: './pages',to: './Resources/pages',filter: ['**/*']}],requestedExecutionLevel: 'highestAvailable'},linux: {target: 'deb',extraFiles: []}
};

2、在需要区分环境的地方获取package.json文件 读取变量 区分代码

3、打包命令修改

"build:win": "cross-env NODE_ENV=production electron-builder --config=electron-builder.config.js -w ",
"buildtest:win": "cross-env NODE_ENV=development electron-builder --config=electron-builder-test.config.js -w",
