打包后的main.js里面存在很多es6的语法，好像是没有转成es5，请问有人遇到这个问题了吗？

`[{
name: "Fee", title: "费用管理", path: "/", access: !1, children: [{
name: "Fee01", title: "仓储费用管理", path: "/feeMang", access: !1, meta: {title: "仓储费用管理"},
component: ()=>n.e(32).then(n.bind(null, 577))
}, {
name: "Fee02", title: "运输费用管理", path: "/feeAtan", access: !1, meta: {title: "运输费用管理"},
component: ()=>n.e(33).then(n.bind(null, 578))
}], component: r.a, icon: "icon-kucun-xianxing"
}];
localStorage.setItem("router", JSON.stringify(l));
var f = [i, c, s, ...l, u, a, o]`
上面是部分打包后的main.js中的代码

Start by inspecting the generated main.js snippet and reproducing the production build. Then trace the repository's webpack and transpilation configuration to determine why ES6 syntax remains. Done means the bundled main.js no longer contains the reported ES6 syntax and the production build still succeeds.
