Angular 6 CLI `Unknown option: '--app'`

Question

I have multiple apps in the same Angular project. After upgrading from Angular 5 to 6 when I try to run:

ng serve --app myAppOne

I am getting this error:

Unknown option: '--app'

It seems that the --app options is not supported any more. What is the best way to specify the app to run in Angular 6?

Answer 1

它不再受支持，这些是可能的替代方案：

ng serve --project=myAppOne

ng serve --project myAppOne

ng serve myAppOne

Answer 2

You can search OldAppName and replace with your new app myAppOne first, then run the project with specific port.

ng serve --project=myAppOne --port 4202

if browser is not automatically opened the url then place it manually
