 i was trying to run my application by using command "ng serve --open" on the command line . 
And getting error localhost/:1 Failed to load resource: the server responded with a status of 404 (Not Found) on 

Also I was working on the other project 2"confusion" which was running on the port 4200. I closed the command line running the project "confusion" and run the ng serve --open command to run my current project namely preschool.
The path of project preschool is:

I am a newbie to angular
