【问题描述】：
在我将 Angular 从 8 升级到 9 后，我实现了 single-spa。当我通过运行命令 yarn serve:single-spa:ibo 开始运行应用程序时出现以下错误。
$ ng s --project ibo --disable-host-check --port 4200 --deploy-url http://localhost:4200/ --live-reload false
As a forewarning, we are moving the CLI npm package to "@angular/cli" with the next release,
which will only support Node 6.9 and greater. This package will be officially deprecated
shortly after.
To disable this warning use "ng set --global warnings.packageDeprecation=false".
The option '--project' is not registered with the serve command. Run `ng serve --help` for a list of supported options.
The option '--disable-host-check' is not registered with the serve command. Run `ng serve --help` for a list of supported options.

无法理解问题。有人请帮帮我吗？
这是我的angular.json 文件：

【问题讨论】：
-
你试过运行 npm install 吗？
-
我正在使用纱线。您的意思是重新安装吗？
-
我的意思是重新安装所有本地依赖。
-
是的，我用 yarn 完成了
-
提供
ng --version的输出
