application 'foo-app' died in status LOADING_SOURCE_CODE: Failed to fetch

[mokedeng]

$ cd examples
$ yarn
$ yarn install:all
$ yarn serve:all

你好，我运行以上4句后，打开F12，控制台报错信息如下：

Failed to load resource: net::ERR_EMPTY_RESPONSE
Uncaught TypeError: application 'foo-app' died in status LOADING_SOURCE_CODE: Failed to fetch

单独运行两个子项目是ok的
请问有解决的方式吗？谢谢

子项目启动时端口号有变吗，主项目开发时是依赖端口号的

[mokedeng]

没变，直接把代码拉下来后运行那4句，就报错了。在win7和win10都试了，报错信息一致

[F-loat]

yarn serve:all 后单独访问 8081 和 8082 都是好的吗

[mokedeng]

单独访问8081和8082是ok的，不能在主页面切换foo-app

[F-loat]

我这儿 mac 没问题，晚上回去用 win 再试下看看，之前应该也都是好的

[F-loat]

还是没复现，你看下主应用加载 foo-app 的请求成功了没，返回的结果是啥

[mokedeng]

端口号没变，安装后运行就报错 在 2020-08-05 18:20:41，"徒言" <[email protected]> 写道： 子项目启动时端口号有变吗，主项目开发时是依赖端口号的 — You are receiving this because you authored the thread. Reply to this email directly, view it on GitHub, or unsubscribe.

看眼网络请求的结果

解决了吗？

通过fetch访问子项目，需要子项目进行可跨域配置，vue.config.js：

devServer: {
headers: {
'Access-Control-Allow-Origin': '*'
}
}

[CIGE-Vince]

配置了
headers: {
'Access-Control-Allow-Origin': '*'
}
还是不行

[CIGE-Vince]

Failed to load http://localhost:8081/: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

配置完后重启子项目

感谢，修改子应用的webpack后重启项目，成功解决
