我有一个有角度的项目，我想在移动设备上使用 ionic。我做到了ionic init。
当我运行命令时ionic serve，我收到此错误：
> ng.cmd run app:serve --host=localhost --port=8100
[ng] Error: Unknown arguments: host, port
[ERROR] ng has unexpectedly closed (exit code 1).
The Ionic CLI will exit. Please check any output above for error details.
这是我的package.json：

[ng] Error: Unknown arguments: host, port
[ERROR] ng has unexpectedly closed (exit code 1).
The Ionic CLI will exit. Please check any output above for error details.
