webpack配置报错！

Question

module:{

rules:[
    {
        test:/\.js$/,
        use: 'babel-loader',        include: /src/,        exclude: /node_modules/
    }
]

}

加上use: 'babel-loader'这个就报错，注释掉就不报错！

npm i @babel/preset-react{    "presets": ["@babel/preset-env","@babel/preset-react"] }学会google查 报错信息哦～
