vue-cli3 同时按需引入vant和element ui

约定不等于承诺〃 2023-07-04 11:28 17阅读 0赞

### 一、安装vant和element ui ###

1.安装vant

# 通过 npm 安装
    npm i vant -S
    
    # 通过 yarn 安装
    yarn add vant

2.安装element ui

npm i element-ui -S

### 二、配置按需引入插件 ###

1.vant

npm i babel-plugin-import -D

2.element ui

npm install babel-plugin-component -D

ps：这里将同一个命令写两遍，是因为我遇到了按需引入element ui后，在引入vant时不生效，当我重新执行了“①安装vant；②配置按需引入；”后，引入vant才生效。

### 三、babel.config.js ###

配置方式一：

module.exports = {
      presets: [
        '@vue/cli-plugin-babel/preset',
      ],
      "plugins": [
        ["import", {
          "libraryName": "vant",
          "libraryDirectory": "es",
          "style": true
        }],
          [
            "component",
            {
              "libraryName": "element-ui",
              "styleLibraryName": "theme-chalk"
            }
          ]
        ]
    }

配置方式二：

module.exports = {
      presets: [
        '@vue/cli-plugin-babel/preset',
      ],
      plugins: [
        ['import', {
          libraryName: 'vant',
          libraryDirectory: 'es',
          style: true
        }, 'vant'],
          [
            "component",
            {
              "libraryName": "element-ui",
              "styleLibraryName": "theme-chalk"
            }
          ]
        ]
    }

### 四、vant.js和elementui.js ###

1.vant.js

ps：示例中只演示了button的引入

import Vue from 'vue';
    import { Button } from 'vant';
    
    Vue.use(Button);
    ...
