The solution to the problem that the new version of vue-cli 3.0 is compatible with ie11

At present, the new versions of vue3.0 and vue2.0 have made great changes in the way of writing, including the issues of file packaging and ie compatibility. The ui framework I use is iviewAdmin. I have searched the Internet for a long time and it is all about the modification of vue2.0. It is in the build folder, so it can’t be used at all, and then I found the following method

The normal steps are divided into six parts:

    1. Change the webpack-dev-server version to 2.71 or 2.11.1.

npm install --save-dev [email protected]

     2. Install @babel/polyfill

npm install --save @babel/polyfill

    3. Main.js code is added at the front

import '@babel/polyfill'

   4. Delete all language packs related to main.js

1.main.js中的以下三部分注释掉：
//import i18n from '@/locale'

Vue.use(iView, {
// i18n: (key, value) => i18n.t(key, value)
})

new Vue({
el: '#app',
router,
// i18n,
store,
render: h => h(App)
})

2.还需要把components\main下的：

// this.setLocal(this.$i18n.locale)
两段注释掉

  5. Modify the configuration file

编辑.babelrc
{
  "presets": [["@vue/app", { "useBuiltIns": "entry" }]]
}

编辑vue.config.js

  transpileDependencies: ['tree-table-vue', 'iview'],

  chainWebpack: config => {
    config.entry('polyfill').add('@babel/polyfill')
    config.resolve.alias
      .set('@', resolve('src')) // key,value自行定义，比如.set('@@', resolve('src/components'))
      .set('_c', resolve('src/components'))
  },

   6. Delete TreeTable dependency

在main.js注释掉

// import TreeTable from 'tree-table-vue'
// import VOrgTree from 'v-org-tree'

以及

// Vue.use(TreeTable)
// Vue.use(VOrgTree)

This is the normal six parts that can be compatible with ie11 (personally tested it, I think it can be compatible as long as the two components of tree-table-vue and v-org-tree are not used)

     Finally, I found a solution for compatibility with v-org-tree. ( https://download.csdn.net/download/qq_39215166/11367811 ) This is my download address. To be honest, I didn’t want to set up c coins Yes, but this website randomly generates c coins for me to download, and I have no choice

There is no compatibility with the tree-table-vue component for the time being. If there is a compatible partner, I hope you can share it.
