嗨,大家好我在一个应用程序工作了2个月,它从来没有过。今天我输入了离子发球,它给了我一个空白页面。我再次再次尝试;没有改变。

控制台的错误是这样的:

```
Failed to load resource: the server responded with a status of 404 (Not Found)
vendor.js Failed to load resource: the server responded with a status of 404 (Not Found)
main.js Failed to load resource: the server responded with a status of 404 (Not Found)
vendor.js Failed to load resource: the server responded with a status of 404 (Not Found)
main.js Failed to load resource: the server responded with a status of 404 (Not Found)
main.css Failed to load resource: the server responded with a status of 404 (Not Found)
```

然后我在互联网上搜索解决方案并尝试:

```
npm uninstall -g cordova ionic
npm install -g cordova ionic
```

但它没有用!

所以我记得,一旦我之前备份了我的app文件夹。所以我试过,看到它的工作原理。我将备份文件夹的www / build文件夹文件复制到我最新的app-folder中。并再次运行离子服务。它自动删除所有文件,但不起作用?

我无法提供我的应用程序?请帮助我们。我没有做任何接受这个错误我感到震惊!

终奌站:

尝试在8102端口提供应用程序。我不知道你是如何管理它的。但是您更改了构建可用的端口。因此,请运行以下命令:

$ ionic serve --p 8102

我找不到解决方案,幸运的是我最近支持了这个项目。我不知道我对主文件夹做了什么,但我的备份文件夹运行良好。我做了完全相同的更改(更新)及其工作。
