title: ng serve command not working after updating to the latest Angular CLI
body: <p>After updating to the latest version of Angular CLI, I am not able to execute the <code>ng serve</code> command any more. However working with <code>yarn start</code> or <code>npm start</code> does allow running the <code>ng serve</code> command  as usual.</p>
  
  <p>Tried installing the latest CLI version for Angular, however nothing helped.
  Following is the Command Prompt snapshot for reference.</p>
