Error: Cannot find module 'babel-plugin-component'

解决方法

1.安装：babel-plugin-component

npm install babel-plugin-component -D

2.在目前的vue脚手架项目中，更改：babel.config.js中的配置，把es2015改为@babel/env。如：

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