Angular kann nicht geladen werden, da die ausführung von skripts auf diesem system deaktiviert ist

This error I encountered when I tried to use integrated terminal of visual studio code for executing Angular CLI commands for the first time.

Exception Details:

\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.

CategoryInfo : SecurityError: (:) [], PSSecurityException

FullyQualifiedErrorId : UnauthorizedAccess

Problem

The issue appear to be security related exception. Also we can observe Unauthorized Access as error Id in exception details.

So the issue is Visual Studio Code could not load ng.ps1 file due to security reasons. Also exception is suggesting to refer Microsoft website article as Visual Studio Code is Microsoft product.

Solution

To solve the issue I could navigate to the file and deleted the ng.ps1 file as shown in below screen shot. After deleting that file I could go ahead with Angular CLI command execution in Visual Studio Code integrated terminal.
