[maoxiaoke]

icestark 是哪个版本的

[WITfeng]

我也有这个问题，子应用icestart版本是2.7.1

[yiescc]

icestark

2.4.2

[maoxiaoke]

https://micro-frontends.ice.work/error/?code=1&arg=/seller @yiescc 这个错误跟这个是一致的，看下是否可以有帮助

[ChenLeoXX]

有解决吗，基于vue-cli构建的 按照文档配置了 umd，还有umd名称 还是报这个错，查看window.microApp这个属性有值，但是status是not-lodaed

可以贴一下子应用配置

[ChenLeoXX]

vue2.0 CLI配置 main.js 配置

[ChenLeoXX]

打包出来后 因为可能有异步懒加载的路由 和组件 会分chunk文件 和入口文件，主应用配置信息使用url 就会报 没导出。

[maoxiaoke]

@ChenLeoXX 可以移除懒加载试下
