vue 3.0 项目搭建移动端 (七) 安装Vant

# 通过 npm 安装 

npm i vant -S

安装完配置

babel.config.js

 

 

module.exports = {
  presets: ['@vue/app'],
  plugins: [
    'lodash',
    [
      'import',
      {
        libraryName: 'vant',
        libraryDirectory: 'es',
        style: true
      },
      'vant'
    ]
  ]
};

运行后报错

 

 先安装插件

# 安装 babel-plugin-import 插件
npm i babel-plugin-import -D

再次运行，但是这里配置了‘lodash',如果去掉可以正常运行，如果不去掉，还要添加

npm i lodash -D

npm i babel-plugin-lodash -D

然后再运行 OK
