vue中Element组件使用报错，Error: Cannot find module ‘babel-preset-es2015‘

将babel.config.js（Element官网中说的 .babelrc）中的

["es2015", { "modules": false }]

修改为

["@babel/preset-env", { "modules": false }]

// babel.config.js

module.exports = {
  presets: [
    '@vue/cli-plugin-babel/preset',
    ["@babel/preset-env", { "modules": false }]
  ],
  "plugins": [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}
