要运行babel命令，您需要安装babel globaly或通过将其保存在脚本中从var adVideoContainer = document.getElementById('ad-video'); var adDisplayContainer = new google.ima.AdDisplayContainer(adVideoContainer); var adsLoader = new google.ima.AdsLoader(adDisplayContainer); adDisplayContainer.initialize(); 运行它

package.json

并使用

运行

scripts: {
   babelCmd: "babel src/app.js --out-file=public/scripts/app.js --presets=env,react --watch"
}

如果要直接运行babel命令，则需要安装

npm run babelCmd
