[Angular-CLI-6]Could not determine single project for 'Serve' target

I have updated my angular-cli with the help of ng update @angular/cli command. After that, I have got an error as Could not determine single project for 'server' target with following error trace.

Could not determine a single project for the 'serve' target.

  },

Did you follow all three steps of the update process?

The update generally follows 3 steps, and will take advantage of the new ng update tool.

1) Update @angular/cli:

npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli

2) Update your Angular framework packages:

ng update @angular/core

3) Update other dependencies

See toward the bottom of this post for more information: https://blog.angular.io/version-6-of-angular-now-available-cc56b0efa7a4
