The serve command requires to be run in an Angular project, but a project definition could not be found

I developed an application ( angular2 nodejs), but now when I open it, I get the following error:

The serve command requires to be run in an Angular project, but a project definition could not be found.

I do not find the problem knowing that I made an update to the cli

Here are some tips that might be useful for this case:

  1. Be sure you are in the root folder when you run ng serve
  2. Use npm install
  3. use npm start

This worked for me, delete or rename 'angular.json' then create a new one.

ng update @angular/cli

You may also need up update typescript if you get error.

Also follow the step here: https://update.angular.io/
