uni-ui使用疑问

HBuilderX 版本1.5.2.20190121
使用 uni-ui
在 script 中引用组件：

import {uniBadge} from '@dcloudio/uni-ui'
//import uniBadge from '@dcloudio/uni-ui/lib/uni-badge/uni-badge.vue' //也可使用此方式引入组件
export default {
components: {uniBadge}
}
此方式能够正常使用；

// main.js

import {uniBadge} from '@dcloudio/uni-ui'
//import uniBadge from '@dcloudio/uni-ui/lib/uni-badge/uni-badge.vue' //也可使用此方式引入组件

Vue.component('uni-badge',uniBadge) //注意组件名必须是一个静态字符串
此方式编译错误；（编译到微信小程序/5+app）
错误信息如下：
Module build failed (from ./node_modules/@dcloudio/webpack-uni-mp-loader/lib/main.js):
