【问题描述】：

Internet Explorer 11 和 Microsoft Edge 在加载我的 Vue 应用程序时显示一个空白页面。控制台日志显示指向 vue.esm.js 中“throw e”行的“未知名称”错误：

Watcher.prototype.get = function get () 
pushTarget(this);
var value;
var vm = this.vm;
try 
value = this.getter.call(vm, vm);
 catch (e) 
if (this.user) 
handleError(e,vm, ("getter for watcher \"" + (this.expression) + "\""));
 else 
    throw e // UNKNOWN NAME ERROR (IE and Edge) 

 finally 
// "touch every property so the are all tracked as

我在 vue-router 中懒加载路由，例如：

const Home = resolve => 
  require.ensure(['@/components/Home'], () => 
    resolve(require('@/components/Home'))
  )

我在加载“主页”组件时遇到错误。 Chrome、Firefox 或 Safari 都没有问题。

【问题讨论】：

你是否使用了一些计算属性，我在使用 IE 时遇到了问题

【参考方案1】：

我发现了问题 - 是我的错误（语法）。我的 v-for 循环中有 :key:="xyz"（应该是 :key="xyz"）。
