title: Why powershell does not run Angular commands?
body: <p>I have started to learn Angular but I note that powershell in Windows gives me an error whenever I make an angular command like:</p>
  
  <pre><code>ng new new-app
  </code></pre>
  
  <p>or</p>
  
  <pre><code>ng serve
  </code></pre>
  
  <p>this is the error what I got:</p>
  
  <pre><code>ng : File C:\Users\&lt; username &gt;\AppData\Roaming\npm\ng.ps1 cannot be loaded because 
  running scripts is disabled on this system. For more information, see 
  about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

  + ng serve
  + ~~
      + CategoryInfo          : SecurityError: (:) [], PSSecurityException
      + FullyQualifiedErrorId : UnauthorizedAccess
  </code></pre>
  
  <p>P.S. I try these commands in cmd and it works.</p>
