vue中引入vant-ui

1、全局引入

import Vant from 'vant';
import 'vant/lib/index.css';
Vue.use(Vant);

2、局部引入

2-1、安装依赖

yarn add vant babel-plugin-import

2-2、配置babel.config.js

module.exports = {
  plugins: [
    ['import', {
      libraryName: 'vant',
      libraryDirectory: 'es',
      style: true
    }, 'vant'],
    ["@babel/plugin-syntax-dynamic-import"]
  ]
};

//解决组件不能动态引入的问题
["@babel/plugin-syntax-dynamic-import"]
