mpvue 转uni-app，编译的时候报错：无法使用对象扩展符

由于mpvue各种坑爹，公司业务需求需要转uni-app，按照教程尝试了一下，打包npm run dev:mp-weixin，出现报错如附件。我尝试了babel-loader的各种兼容es6的配置，但是都无效，然后我对比了官方的例子，babel配置一样，但是我这边会报扩展符为无效语法。

这是我的babel.config.js文件

const plugins = []  

process.UNI_LIBRARIES = process.UNI_LIBRARIES || ['@dcloudio/uni-ui']  

process.UNI_LIBRARIES.forEach(libraryName => {  
  plugins.push([  
    'import',  
    {  
      'libraryName': libraryName,  
      'customName': (name) => {  
        return `${libraryName}/lib/${name}/${name}`  
      }  
    }  
  ])  
})  
module.exports = {  
  presets: [  
    "es2015",  
    'stage-2',  
    [  
      '@vue/app',  
      {  
        useBuiltIns: 'entry'  
      }  
    ]  
  ],  
  plugins  
}
