都已经安装好了babel-loader,babel-preset-react也安装了

const path=require('path')

module.exports={
entry:{
index:'./src/script/index.js'
},
output:{
path:path.resolve(__dirname,'build/script'),
filename:'[name].js'
},
module:{
rules:[
{
test:/\.js$/,
include:[path.resolve(__dirname,'src/script')],
loader:'babel-loader'
}
]
}
}
