复现步骤

源码

// config/index.js

import { resolve } from 'path'

  alias: {
    '@vant-weapp': resolve(__dirname, '..', 'node_modules/@vant/weapp/dist')
  },

// pages/index/index.config.js

export default {
  navigationBarTitleText: '首页',
  usingComponents: {
    'van-button': '@vant-weapp/button/index',
    'van-calendar': '@vant-weapp/calendar/index'
  }
}

## 报错信息

```shell
[ dist/pages/index/index.json 文件内容错误] dist/pages/index/index.json: ["usingComponents"]["van-button"]: "@vant-weapp/button/index" 未找到

补充

taro -cli 2.x 会这样编译解析：

// packages/taro-cli/src/weapp.js 

 Object.keys(usingComponents).map(async item => {
      const componentPath = usingComponents[item]
      let componentPath = usingComponents[item]

      if (Util.isAliasPath(componentPath, pathAlias)) {
        componentPath = Util.replaceAliasPath(configFile, componentPath, pathAlias)
        usingComponents[item] = componentPath
      }

期望结果

路径别名可以被正确解析

实际结果

路径别名可以未能被解析
