Javascript 编译ES6和VUE JS不适用于IE 11

因此，我对IE11中的ES6、Webpack和VUE JS存在问题。这适用于Edge、Chrome、Safari和Firefox，但不适用于IE11

错误：

SCRIPT1002: Syntax error
vue.js (16,8498)

好的，那么这条线是什么

(module,__webpack_exports__,__webpack_require__){"use strict";eval("/* unused harmony export getJSON */\n/* unused harmony export getScrollBarWidth */\n/* unused harmony export translations */\n/* harmony export (immutable) */ __webpack_exports__[\"b\"] = delayer;\n/* unused harmony export VueFixer */\n// coerce convert som types of data into another type\nconst coerce = {\n  // Convert a string to booleam.

Otherwise, return 0.\n  number: (val, alt = null) => (typeof val === 'number' ? val : val === undefined || val === null || isNaN(Number(val)) ? alt :

这会持续一段时间

我被这一团糟弄糊涂了，我相信你也是：

这是我的网页包文件：

我还安装并完成了：

import“@babel/polyfill”在
boot.js
中，我们有

我不确定除了“语法”之外还有什么错误我缺少什么吗？
如前所述，IE11不支持ES6。查看抛出该错误的代码行，您将很快找到ES6功能（例如箭头函数）

Polyfilling不会为您提供使用ES6的能力，您唯一能做的就是将ES5作为目标

您可以通过编辑您的
babelrc
（适用于Babel 7）来实现这一点：

如果您仍在使用Babel 6，根据以下说明，您应该能够像这样使用它：

{
  "presets": [
    ["env", {
      "targets": {
        // The % refers to the global coverage of users from browserslist
        "browsers": [ ">0.25%"]
      }
    }],
    "vue"
  ]
}

这似乎是一个更好的答案，什么是
@vue/app
？我正在使用的是
{“预设”：[“env”，“vue”]}
是否有用于
@vue
的巴贝尔预设空间？
@vue
空间是当前版本的vue cli和与之相关的所有内容（v3）-这仅与巴贝尔7兼容。如果您仍在使用6，我想通过将这些选项嵌套在“env”数组中也可以实现同样的效果。我会更新我的答案，但我不能100%确定它是否适用于babel 6。我应该把这个放在哪个文件中？@JSmith这需要放在你的babel配置文件中。大多数情况下，当我尝试将此预设与
@babel/preset env
一起运行时，它被命名为
.babelrc
，就像这样
['@babel/preset env'，{modules:false}]，我得到一个错误-require没有定义
{
  "presets": [
    ["env", {
      "targets": {
        // The % refers to the global coverage of users from browserslist
        "browsers": [ ">0.25%"]
      }
    }],
    "vue"
  ]
}
