asp.net-core - IE11 的 Vuetify/Lib Polyfilling 不起作用 - SCRIPT1002 : Syntax Error

Question

我尝试使用通常的 import Vuetify from "vuetify/lib" 来引用 vuetify/lib，但是当我这样做时，应用程序会在 IE11 中因 SCRIPT1003:应为“:”。

如果我更改对 import Vuetify from "vuetify" 的引用 - 没有 /lib 部分 - 它不会抛出错误。

请注意，我实际上还没有在任何地方使用 vuetify。我没有任何 Vuetify 组件或调用；我只是添加库。

现在我表面上已经包含了 vuetify 并被 IE11 愉快地解析，我想使用其中的一些组件。如果我在模板中放置任何 vuetify 组件，IE11 会抛出 Script1002:语法错误 消息。

有人有建议让它真正发挥作用吗？

在我这边，SCRIPT1002:语法错误已通过更新webpack-dev-server解决。

尝试将 webpack-dev-server 版本更改为 3.8.2 并删除 node_modules 和 npm install再次。

还有一个。

//.babelrc

{
  "presets": ["@babel/preset-env"]
}

//babel.config.js

module.exports = {
  presets: ['@babel/preset-env']
}

You can install vuetify in three ways:

default installation

The first (and recommended) way is to utilize the vuetify-loader or what we call automatic A-la-carte. This will ensure that your application only uses the features and styles from Vuetify that are needed, significantly reducing your application's compiled size and is setup you will see in a new vue-cli-3 project. Keep in mind, when importing from vuetify/lib, the necessary styles are automatically imported for you.

vue-cli a-la-carte installation

You can also manually import individual components without the need for the vuetify-loader. This is considered manual A-la-carte.

(And about your done: import Vuetify from 'vuetify')

vue-cli full installation

The last method will import and setup all of Vuetify's features and styles. As stated above, it is still recommended that you utilize the vuetify-loader if at all possible. For this install, you will need to manually import the Vuetify styles. This is also the process used when bootstrapping Vuetify through a browser as opposed to compiling.

import Vue from 'vue'
import Vuetify from 'vuetify'
import 'vuetify/dist/vuetify.min.css'

Vue.use(Vuetify)

const opts = {}

export default new Vuetify(opts)

祝你好运。
