我想在一个vue项目用web worker 处理高并发的socket，想在里面用ES6模块所以配置了worker-loader，结果编译后经常拿不到worker脚本Uncaught SyntaxError: Unexpected token '<'

main.js :

import Worker from './workers/socket.worker.js'
Vue.prototype.$priceWk = new Worker()

socket.worker.js :

onmessage = (event) => {
    if (!event) return;
    const { type, payload } = event.data;
    console.log( type, payload )
}

webpack.config.js :

{
    test: /\.worker\.(c|m)?js$/i,
    loader: 'worker-loader',
    options: {
        filename: (pathData) => {
            if (/\.worker\.(c|m)?js$/i.test(pathData.chunk.entryModule.resource)) {
                return '[name].js'
            }
            return '[name].worker.js'
        },
    }
}
