element-ui按需引入报错Cannot find module 'babel-preset-es2015' 及多组件引入报错

一、elementUI按需引入报错。Error: Cannot find module 'babel-preset-es2015' from 'XXX'

根据elementUI官方文档,按需引入组件。

第一步:安装插件

npm install babel-plugin-component -D

 

第二步: 将 .babelrc 修改为:

{
  "presets": [["es2015", { "modules": false }]],
  "plugins": [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}

但是报错了。 Error: Cannot find module 'babel-preset-es2015' from '/Users/kangxiaoxiao/Documents/workspace/demo'

 

解决办法如下:

1、安装插件 @babel/preset-env

npm i @babel/preset-env -D

2、将 .babelrc中的 es2015 改为 @babel/preset-env

{
  "presets": [["@babel/preset-env", { "modules": false }]],
  "plugins": [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}

  

二、多组件引入样式

babel-plugin-component上的文档说明如下:

{
  "plugins": [xxx,
    ["component", {
      libraryName: "antd",
      style: true,
    }, "antd"],
    ["component", {
      libraryName: "test-module",
      style: true,
    }, "test-module"]
  ]
}

但是。。实在是写得太简单了,怎么引入都报错,经摸索,可以如下:

{
  "presets": [["@babel/preset-env", { "modules": false }]],
  "plugins": [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      },
      "element-ui"
    ],
    [
      "component",
      {
        "libraryName": "mint-ui",
        "styleLibraryName": "theme-chalk",
        "style": true
      },
      "mint-ui"
    ]
  ]
}
