4创建 babel.config.json 配置文件
Great! You've configured Babel but you haven't made it actually do anything. Create a babel.config.json config in your project root and enable some presets.
To start, you can use the env preset, which enables transforms for ES2015+
npm install @babel/preset-env --save-dev
In order to enable the preset you have to define it in your babel.config.json file, like this:
{
"presets": ["@babel/preset-env"]
}
