package.json中需要引入以下依赖：
开发依赖：
"@babel/core": "^7.1.2",
"@babel/preset-env": "^7.1.0",
"@babel/preset-react": "^7.0.0",
"babel-loader": "^8.0.4”,
运行时依赖：
"react": "^16.6.0",
"react-dom": "^16.6.0"
webpack.config.js中需要增加以下模块解析处理规则：
{
test: /\.m?js$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'babel-loader',
options: {
presets: ['@babel/preset-env']
}
}
