title: the term ng is not recognized as the name of a cmdlet in angular
body: <p>I'm very new to angular and i am learning from a project that has been developed some months back.</p>
  
  <p>node v is 12.13.1
  npm v is 6.12.1</p>
  
  <ul>
  <li>I'm working in windows Operating system.</li>
  <li>when i tried ng --version or ng -v or ng v it is showing "the term ng is not recognized as the name of a cmdlet in angular".</li>
  <li>But using npm list -global --depth 0 shows me that @angular/cli@8.3.21.</li>
  <li>to run the application im using npm start since ng serve is not working.</li>
  </ul>
  
  <p>I tried Updating angularCli by following the steps given in the below link but still the same.
  <a href="https://www.npmjs.com/package/@angular/cli" rel="nofollow noreferrer">https://www.npmjs.com/package/@angular/cli</a></p>
  
  <p>please help me to solve this issue.
  Thanks in advance.</p>
